Gents,

Do any of you know of any comprehensive (preferably with pictures) guides / instructions for stripping & assembling the BSA Mercury S?

I've had a bit of a search online but there doesn't seem to be anything on youtube and the only diagrams I've found are the ones for parts, such as on the Chambers site.

I'm going to be fitting a Welsh Willy kit to mine along with new piston head/seal/buffer washer however most of the stuff I've found via google seems to suggest the Titan spring is a 'bit harsh' when fitted to the Mercury... I don't know if the one in the WW kit is cut down to standard Mercury length when he sizes the guide/tophat to it.

Just for info, the rifle I've just got hasn't been used in 37 years, hence the need for a bit of a service!

Advice would be greatly appreciated.
