Spares or borrow

[gasman]

Hi I’m trying to rebuild a Silk 700s engine and gearbox but I’m missing a few parts.

1. The (27 tooth) ? gear that turns the clutch sleeve gear

2. The clutch operating ring (outer, I’ve got the inner)

3. Head gasket

4. 🤣 oil pump if one is available

5. Primary chain tensioner

Even if I could borrow any part so I can make one or if someone could provide drawings with dimensions

Thanks all

I have a primary chain tensioner. Also a pair of pistons!
