Can you post a picture of the Action photographed from the TOP
and side.

Also, post ANY LETTERS / MARKS etc from the barrel and action
including the proof marks and serial no's.

Sounds like you have a nice piece. I used to have a
Holland Underlever Hammer in 500/450 3 1/4" which
used to be owned by Graeme Wright - it's mentioned in his book
somewhere.

Hope this helps.
