All - am looking for one of these cases... it would normally be found inside the Sherman Firefly to hold the Striker Mechanism (or more probably a spare striker mechanism).
Unfortunately the example I photographed was too tightly wedged in what is the metal frame to hold the WS19 spare valve case, that I could not budge it.
Note the case has a round protrusion at the base.
If anyone has one they don't need, please let me know.
If you have one I can pattern from that may be good too - though of course I know where there is one, but being able to borrow that one, am not sure yet.
Cheers
Tim
