Couldn't make that up. Nice one.
I would stash the 45 and leave it well alone for a rainy day.
Fettle the 35 but your going to be limited as to what you are going to achieve. I think a spit and polish should be sufficient.
Same story with the BSA.
Apologies but springers are not my thing. I'm sure some tart on here will know what they are on about.
