[QUOTE="davidd, post: 48635, member: 1177"] Edmundo, I think in general there was one outer tank shape that had a few variations. Then, there are all the special tanks. The stock tank kept its basic design. Modifications over the years included adding tabs for the cross-tie to prevent cracking, enlarging the carb cut-out underneath and the Series D changes which included eliminating the oil hole and narrowing the tunnel for extra capacity. The special tanks were probably made by several firms. John Bland mentioned Homers of Birmingham as one possibility. I suspect the choice was affected by availability of the finished tank more than anything else. Some modifications I am sure could be done in house, like the addition of two more petrol taps for fuel burners or underside mods for big carbs. Many of the large tanks were built on a stock tank. I believe if a damaged tank came in that was beyond repair it would be handed to the tank shop. The shop would use the tunnel and the rear of the tank to speed up the fitting and then fabricate the rest of the bottom and top to suit the purpose. On the Grey Flash TT tanks, the photo below may be one, there is an additional crossover tie in the front and the oil filler chase is much larger allowing easier fitting. The photo of the rear shows how similar the lower shape is to the original stock tank. This is also how the large tank on Gunga Din appears. This is speculation on my part, but if I were building a big tank I would love to have a damaged tank to provide the tunnel and the mounting points.
