Hi NormK, Your are almost guaranteed to profit well from that haul. Here's a thumblatch catcher I successfully mended using my hot staple set you put me onto. I added a bracket on the end as it's a high stress point as it goes on and off the mower. It would fit on your FC high arch unless it's an early 70s VC series.
The beauty of this is you can't see it externally. Cutting the staple stems is the only down side and it leaves a sharp spike of metal, so you have to watch where you do it.
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
