I love this model. Many were made with that top cover style. I got one for $13 on EBay. I like the look of the mark 2 better with it's bigger rear wheels so I converted mine to ball bearing wheels. The rear axle is slightly different so I swapped it out from a spare chassis I bought on EBay for parts. It feels lighter to push.

Good job sorting yours out.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
