Its got assisted opening and the action is tight , bores are good, theres an odd mark on the lower stock , not sure if its been put there deliberately on just banged , also an interesting crown logo .She’s certainly a fixer upper.
Year is 1928 or 29.
Unusual top rib.
I couldn’t give a fair appraisal on the barrels without seeing it in the flesh and measuring the wall thickness. Might just need a light polish and reblacking which is a 100 quid job. Might need new barrels which is a 12 grand job (if you get it done properly by Purdeys).
Again hard to give a value without knowing the full condition. More than 4 less than 10.
