Hi Ted,

I have an Ugartechea 28 ga marked 'Churchill Royal'. It certainly is not an English Churchill, but it is a decent knockabout upland gun.

It sounds similar to yours, but it has a straight grip and does not have a third fastener. Looks like photos I have seen of the M30.

Anyway, I really like your idea of carrying spare strikers. Do you remember where you found yours and the 3-pronged tool to remove the disks?

Thanks
