I recently inherited my grandfather's Belknap anvil.  The serial number is either 87420 or 37420, anyone out there with a copy of AIA that could shed some light on the history?  My family is from Louisville and the "knap" is the only identifiable part of the original logo stamp, so I assume it was a licensed A&H from the early 1900's.  The edges are still sharp and the striking face is dead flat, I never knew my grandfather so I feel extremely lucky to have this piece of history connecting us.  

Pictures?

Here is the only picture that I currently have of it, it does have the pill indent on the underside and has the steam hammer marks on the underside of the heel.

If it is an Arm & Hammer than Anvils in America says that it's from the year 1922-1923 for serial number 37420. Arm & Hammer Anvil serial numbers never went up to 87420

awesome, Thanks for the info!

Could you post a closeup picture of the side logo stamp, and another of the serial number?   I'd like to add it to the A&H logo database.

sure thing, unfortunately the side logo was poorly stamped intially and time has not helped it stick around, but here's what I can get.

If you dust it with chalk, flour, etc and wipe it off lightly it'll help make punched characters stand out. Using oblique lighting is also a big help and works on punching or cast proud.

Thanks for the pics!
