I am about to buy a repro chain oiler tank from John Rose (who, incidentally, did a great job recovering my saddle in leather and does some very nice repro leather fronted toolboxes, one of which I also bought).
He has two types of tank. One is the small cylindrical unit that allows the fitting of a mag/dyno and the other is the larger ‘box’ type.
The question is, would one type be correct for a 1930 TT Rep, or were they both offered by Scott for selection by the purchaser?
Obviously, if the bike had lights, the larger unit couldn’t be fitted, which may suggest it was used for competition bikes only (or not, as the case may be).
Hi, The 1928 works TT bikes, and the first TT Reps, in late 1928, had the angular ‘trapezoid’ shape tank fitted, usually as an extra, and this continued into 1929. It was soon realised that they obstructed the fitting of a Magdyno, and that they were more expensive to make than a simple cylindrical type, so they were discontinued some time in the first half of 1929, and replaced by the cylindrical type, which was also fitted as an extra on the Flying Squirrel Deluxe and the Sprint Special. Incidentally the works bikes had the filler neck and cap on the left-hand side, but production bikes had them on the right-hand side. I have no idea why they bothered to change that detail !
