G'day
Captrusty,
Tyres are shagged can they be replaced ?
Rims wobble around on axles can this be fixed ?
Depends on where the wear is. If it's in the wheels, rebushing may be possible. Worn stub axles are a bit more difficult to replace, but still possible. Dunno about the tyres, but one of the other ODK denizens may..
How was the throttle cable originally attached to handle bars ?
It was run under those two heavy gauge aluminium ties that secure the snorkel.
Can you still get clamps for the snorkel ?
Not sure exactly what you're asking here. The ties are the original setup for this long snorkel, not two-piece clamps as the later models used. Repros are available on Fleabay, but ain't cheap. A search for 'Victa snorkel' will bring them up.
What you have there appears to be a quite original Victa 18 Model Four Special, around 1957-8 vintage.
We have a bit of a megathread on the Model 4 and 5's, as the early Model 4's were built as the ill-fated 'Automatic' version.
