400NE:
Unfortunately the Jeffery ledger page I have in my possession only covers SNs 25581 to 25590, though whoever picks that gun up will be able to get the goods from the current owner of the records for sure. I take it you've examined the sidelock personally, as the 4-digit number does not appear in the on-line photos I was able to view. Very nice rifle BTW, wish I had a few thou spare for the privelage of looking after it for a while!

The 4-digit number on my .400 BLE is 3362

Welcome to the forum, Leonard. You are a relative I take it? What relation to you was Charles? I too would very much appreciate a cc on any private e-mails as I have a long-standing interest in this topic also! marrakai577@hotmail.com
