I have this one on the way from Track. I've never heard of W. Mander, and have looked through the Birmingham names, as this one has English proofs, but have come up with nothing. If anyone knows more (anything), it would be much appreciated.
I'll fix her up in the shop, correct the chips, cracks, and mainspring, and plan to see if she will be a good field gun, as it looks like she has lots of life left in her.
