Sentinel B40F Beadle B??F (ex C35C)
The years leading up to 1950 spawned a revolution in the design of single-deck buses and coaches, in which, in an effort to increase passenger capacity, the engine was removed from its traditional prominent position "between the shafts", turned on its side, and tucked away ignominiously under the floor. Leyland had built a class of buses to this design for London Transport before the war, and BMMO standardised on it from 1946 for their Midland Red fleet.
Coincidentally, when Sentinel started building diesel lorries in 1946, they mounted the engine horizontally under the cab floor, just as they had done with their famous steam waggons. This experience, together with with the fact that the company was by then part of a group which also made panelling for Beadle bus bodies, placed Sentinel in an ideal position to take part in the underfloor-engined bus revolution. In fact Sentinel was the first manufacturer to offer such a bus on the open market, exhibiting two complete vehicles at the 1948 Commercial Motor Show, while Leyland – who were developing the Olympic – could only show a horizontal engine as a taster.
The first models were the STC4, a lightweight integral product with bus bodywork built by Sentinel to Beadle design, and the SLC4, which was supplied as a chassis for outside bodying as bus or coach, although most were bodied by Beadle as coaches. Six-cylinder models STC6 and SLC6 followed after a couple of years, the latter with a wider choice of bodywork. Unfortunately Sentinel’s reputation in the bus world began as non-existent, started to sink because of early problems with engines and engine mountings, and never really recovered. The company gave up building road vehicles in 1956.
With the exception of Ribble, who were involved in the design process and purchased a total of 20 Sentinels, most buyers were small independents, of which Browns of Donnington Wood in Shropshire was one of the best known. The STC4 shown here was new as a Sentinel demonstrator, and the SLC4 had been converted by the operator from a centre-entrance coach to a front-entrance omo bus by the time these photos were taken in 1968. Both vehicles are still in existence.

"Following GUJ 608′s photo from Peter Williamson, in Brown’s colours.
Here’s a photo I took of her yesterday (6th Nov 2011) at the Aston Manor Museum, Birmingham. The museum officially closed on 30th Oct, but they helpfully let me in. I couldn’t discover whose livery it was painted in, but maybe it was the one it wore whilst a demonstrator, bearing in mind it shows Senitinel in the number box.
Its history, prior to Brown’s ownership, was demonstrator, then Maryland Coaches, East London, for four years, then Warners of Tewkesbury, for four years. The future of the museum’s collection is now uncertain, as they must vacate the building by 31st Dec.."

GUJ 608 is currently in the livery it wore as a Sentinel demonstrator at the beginning of its life, although it is believed that it kept this colour scheme while with Maryland Coaches. Warners repainted it in their two-tone green livery.

I noted with interest the bus painted blue with Dinnington as its destination – Hills of Whiston used to make Sentinel buses and two were supplied to a local company – Wigmore’s that ran between Dinnington and Sheffield – passing
en route Whiston. Could this be one of the two actual buses. They also produced buses for a firm called Camplejohn. Hope this is of some interest !
The destination is Donnington, suggesting that it still has a Browns blind.
As far as I can ascertain, the only Sentinel that ran for Wigmores of Dinnington was JWW 316. Apparently a second one (unidentified) was exhibited in Wigmores livery at the 1950 Commercial Motor Show, but was never delivered.

Ah! Dear old Wiggy’s. As a slip of a boy (13 or so) I wrote to Wiggy’s and got a very nice invitation to their Dinnington depot. At the time it was in the West Riding – hence the registrations – but post 1974 became part of Rotherham, South Yorkshire. [South Yorkshire is geographically correct - if not historically - and better than Humberside. What was wrong with the Ridings anyway? Did the London centric Civil Servants not understand them?]

The original livery was cream/green and it was Donnington, this bus was part a fleet of Sentinels that belonged to H. Brown and Sons, H. Brown being Harry Brown who was my late great grandfather, look at Made in Shrewsbury for history of the Sentinels.
Does anyone know where this bus is now?

The past year has been a torrid time for Aston Manor Museum staff, first moving to what they thought was a secure site, then having to move again. Transferring, by road, some frail items, like part-trams and other barely roadworthy vehicles, proved difficult. They are still near their original site, however and, I assume, GUJ 608 is still with them. They hope to re-open around Easter.

There is an earlier reference to Camplejohn Bros. This company operated in the Barnsley area before being acquired Yorkshire Traction.
They operated a number of Sentinels most of which can be seen here: www.jsh1949.co.uk/

Re the above link to pics of Camplejohn vehicles, the TTC 882 depicted was, as can be seen but not expressly stated, an Atkinson Alpha. All the other vehicles shown were Sentinels – apart from the obvious Dennis Lancet, of course.

Stumbled across the picture of the blue Sentinel. I remember the first of these being operated by A C Wigmore (1949) on their Dinnington to Sheffield service. They seemed so modern and advanced when compared to the cab single deck Leylands, operated by East Midlands. As a small boy, I would always watch for this new bus and I remember keeping a blue chalk drawn sketch of it on the inside of my school desk, all through the year. How I wished to drive one!

I’ve recently had a visit to the new AMRTM site and my report is at www.focustransport.org.uk/ Due to the building’s smaller size many of their vehicles are being stored off site, and I am assuming this is also the case of the Sentinel which is not at the new site. AMRTM now have a facebook page to keep people up to date about their collection.

The AMRTM Sentinel belongs to Richard Gray who is a Director. It is I believe at their off site storage and not on display.
A sister vehicle belonging to Dave Wheatley of Kenilworth is currently undergoing restoration and I understand could be roadworthy in late 2013
