'Tis a puzzlement!

Today, we can only guess at the circumstances surrounding the serial-numbering of a firm's guns, and the length of time between manufacture and actual sale.

...until we peruse the journal entry!

Looks like a letter to the owners of the AH records is in the offing.

One thing: an e-mail or letter to Frank Findlow might shed some light on this, as I know he has trawled through the Henry journals looking for 20/.577 rifles, and has copied many pages. He is also interested in the .577 x 2 3/4 Express, and would be delighted to hear of your acquisition I'm sure (with photos!)

Good luck mate.
