Hello Charlie21,
nice to have another Victaphile join the Victa 2 stroke army lol.
Good on you saving it instead of going down the path of stripping for bits. It looks to have a good body. That top belongs on the lowest priced models with it's smaller fuel cap and more exposed engine.
I quite like the exposed engine look myself.
In the 80's era there were three main tiers of engine dress cowl. Your one shown, a lower slung square one with bigger fuel cap that covered the engine fins, and a more fancy one that sloped at the front beyond the exhaust. I have examples of all three in my collection.
Can we see your Silver Streak? That chassis was way better than the pressed steel version. Does it have a good catcher? They were the weak point as well as erosion of the base in extremely sandy soil and damage from striking rocks and stones.
