While we await the arrival of 46100, it might be of interest to put the rebuilt Royal Scot model into context within the post-WW2 Bassett-Lowke 0 gauge range.
At first two, later three, ‘grades’ of locomotive were offered in the 1950s.
First, there were the models with a lithographed finish, made of tinplate and assembled using the ‘tab and slot’ method. These were mass produced models. All were offered with a choice of clockwork or electric drive. Generally, post-WW2, lithography was used for coloured parts such as boilers, tender sides etc and it included the lining where present. However, company initials, the B.R. lion and wheel emblem, running numbers were applied separately using transfers. All-black parts such as tender frames and tops were usually spray painted. Models of this class were generally well-proportioned but plain, with very little detail. The range included a freelance 0-6-0T, freelance 4-4-0 (the ‘Prince Charles’) and a freelance 0-6-0 tender locomotive. The 0-6-0 tender locomotive was in plain black livery and entirely spray painted with transfers for the running number and B.R. emblem. In B.R. livery, both 0-6-0s were offered with LM or Eastern Region numbers and the chimneys were different, Stanier pattern on the ex-LMS engines. There were two lithographed models depicting real prototypes: the LMS 4-4-0 3-cylinder compound and A1 Pacific ‘Flying Scotsman’. Both these models were quite early reintroductions after WW2 so were initially produced in pre-nationalisation colours. This is the catalogue listing for the Flying Scotsman in 1956:
All the Flying Scotsman models have the same bodies, whether fitted with clockwork or electric motors. There is always a key-hole and a rectangular cut-out in the back-head for the control levers needed on clockwork mechanisms. The clockwork and electric motors are of similar sizes and have identical fixing points. Despite what it says in the catalogue description above, the clockwork and electric motors were also fitted with the same type of cast-iron wheels.
Note the price — £14.0.0 in 1956. This was by far the largest and most expensive of the lithographed models.
The second ‘grade’ of locomotive model offered in the 1950s can probably best be described as ‘semi-mass-produced’. Constructed in tinplate, these models were hand-assembled by soldering together the sheet-metal parts, then hand-painted and lined. Numbers and emblems were transfers. Some of the sheet metal parts were definitely made using press tools. Compared with the lithographed locomotive models, those of soldered construction do look better. There are no unsightly tabs on splasher tops etc, or inappropriate visible gaps between components. The soldered, hand-painted range were more detailed than the lithographed models. Depending on the prototype, standard fittings included smoke-box door handles, vacuum pipes on buffer beams, lamp brackets, hand-rails on the cab and smoke box. Buffers were sprung, visible axle-boxes and leaf springs on tenders and pony-trucks were detailed castings, rather than pressed sheet metal. Leaving aside the live-steam moguls, these models too were offered with either clockwork or electric drive. The motors were the same type as fitted to the Flying Scotsman model. Unlike for the lithographed models, the bodies of electric models in the hand-built range did not have a key-hole or cut-out for clockwork controls in the back-head. In the range of soldered-construction, hand-painted, tinplate locomotive models offered post-WW2 were LMS (then LMR) Pacific ‘Duchess of Montrose’, a Stanier 2-6-4T and the ‘Royal Scot’. As per my previous post, the Royal Scot model as reintroduced post-WW2 was of the locomotive as originally built but with a Stanier tender and in LMS black livery. The B.R. version was of the locomotive as rebuilt with a taper boiler.
This is the 1956 catalogue listing for the Duchess of Montrose:
More than twice the price of the Flying Scotsman.
There were four 0 gauge live steam models post-WW2. Two freelance models, the ‘Enterprise’ 4-4-0 and ‘Super-Enterprise’ 4-6-0. These were hand-painted (soon paint-less, if used) but had tab-and-slot construction tenders. The Gresley and Stanier moguls were of all-soldered construction, with similar levels of detailing to the hand-painted clockwork and electric models described above.
From 1957, Bassett-Lowke offered improved versions of its standard lithographed and hand-painted locomotive models. The upgraded models were marketed as ‘nu-scale’. The enhancements took the lithographed models up to a level of detail on a par with the hand-painted range, though they were still in lithographed finish. Nu-scale versions of the standard models have larger diameter bogie wheels, smaller wheel flanges and were available converted to 2-rail electric.
The third ‘grade’ of locomotive models offered in the 1950s were individually hand-built. These were generally constructed to order, in brass, and were electric only. They were hugely expensive and sold in tiny numbers. This is the 1956 catalogue listing for the GW Castle:
More than twice the price of the Duchess of Montrose.
Later models in this series included a Britannia Pacific (£72) and Deltic (£96). Most of these models seem to have been built by a subcontractor rather than at Northampton. It is believed there were 12 Castles built by Victor Hunt plus an unknown number of an uncatalogued simpler version that was a Northampton product. It has been suggested there were ten Deltic models made, also the work of Victor Hunt. Very few standard Bassett-Lowke parts were used in these models, though I believe the Britannia was fitted with a standard Bassett-Lowke motor, driving wheels and valve gear, as used for the Duchess of Montrose and Flying Scotsman.
Speaking personally, I have never had chance to closely examine any model from the very expensive hand-made range. I’ve seen photos, of course, so I know the model of ‘Deltic’ does not look much like the real loco. The Castle — the Hunt version anyway — is a beautiful model, but it requires very large radius curves. None of the models from this range is ever going to appear at Rivermead Central.
