Murphy,

Yes, the tang is stamped as you mention, which is why I have always identified it as a Miller.

When in Geoffs possession the gun was apart for the forend repairs and a general check-up by a 'smith of good reputation and experience. As I remember (Geoff can correct if I am wrong) the 'smith did not think the mechanism looked like the Millers he had seen.

I won't drag this thread to far off topic since I won't have the time to pull the buttstock/triggerplate for the forseeable future.

Mike
