Nice gun and nice try. While your gun/example is very nicely embellished, it's not quite in the same league as the FH25. Look at the difference in the frame sculpting between your example and the FH25. The FH25 has hand filed frame bolsters, a elegantly sculpted top lever, a proprietary version of intercepting sears, horn insert in the forend, removeable hinge pin, etc.
FH25, circa 1910, notice the sculpting of the frame, pay special attention to the quality of the filing of the bolsters.


Your example does not have intercepting sears, I do not believe it has a removeable hing pin, almost zero sculpting/filing to the frame, fences, etc. These are just some of the differences between the two types of guns. I hope this helps to explain the difference between the two types of guns.
I wish I took pictures of the internal works before I sold my FH25....there was alot of TLC given to the guts of that gun. Everything smooth and polished to mirrors. Absolutely fantastic.
By the way...if the pictured Clabrough was bought for $469 Can.......that is a freeeking steal :-)|
