Great originals Gaz...both nice and accurate. (The 2a is Seemingly perfectly accurate from the Images (With only a slight possibility of it having a Model 1 Rotomo Exhaust).
Note how the circlip carb and pulley continued into the Model 3 Series for a short period,after the 2a was finished.
A handfull of early model 3s recieved the dished pulley and even less got the circlip carb...also the metal cap on the model 3 has been proven to be correct for some early models just like the first handfull of automatics. (Id like too bet the 3 has an early serial).
It shows how often variations in victa models existed,especially at the intersection of those models. Their use of leftover parts was common.
Your blessed to have so many originals mate, im really enjoying seeing them.
