Leech (Rochester) Jinty 0-6-0T

[FourCoupled]

Hi Everyone

I am currently renovating an 0 gauge live steam Leech Rochester Jinty for a pal butI have created myself a problem by losing the safety valve - very embarrassing.

Does anyone have either:
a) a spare valve that I could purchase
b) provide me with pics/sketches and dimensions of the 5 main components
c) lend me a valve (I'm in the UK) that I could use to produce drawings of the components
d) give me a steer on where I might be able to locate a replacement.

I would, of course, reimburse all reasonable expenses.

I have attached a phot of the loco for reference, including the safety valve before I lost it.

Many thanks for reading this and any help would be really appreciated.

Bruce
