What a little beauty Scott! Early To Mid 1956...Shes A very early Model 2 running the model 1 chassis. Every thing I can see appears accurate. You will need smily face choke (red Victa print) Model 2 Badge with 18" (both digits exact height),metal cap and fuel tap(this one is accurate Rotomo,but is for a later version). Thats it!
I Would need to see the engine parts stripped in order to determine accurately the barrel and head style,to see if these parts also carried over from the model 1 as well as the chassis.
Its my opinoin this is factory correct,as alot of the early models around the transition between model 1 and 2 often got leftover parts from the Model 1. This is especially common of the brass nut carby,barrel,head assy and chassis.
Chassis model 1
Throttle model 1
Barrel and head (unsure at this stage)
Carby Model 2
Engine model 2
Muffler model 2
Fuel Tap Model 2(late) Model 2a,Model 4 Automatic.
Top hat (unsure as I cant see the Images,if the chamfer on the top edge is barely visible its a model 1,if its prominent,then model 2.
Can clarify the unsures with better images
An Awesome little Rotomo Scott,Id dearly love this one...Well scored.
