I've got a cap lock double barrel I'm trying to find some info on it if anyone can help. The locks have "E. W. Harrold" on them. I don't know if this is the gun maker or the lock maker. On the gun itself the only writing I can find is "Laminated Steel" which is on the rib between the barrels (I have not removed the barrels to look on the underside of them). The right bore measures .723 and the left measures .728. There is quite a bit of scroll work on the lock, tang, etc. Is anyone familiar with Harrold?? Thanks for your help.
