I prepared a study of the Whitmore & Wolff company and its successors, whose imported locks are sometimes seen on Pennsylvania long rifles. They are probably found Ohio and Kentucky-made rifles too, since the company advertised widely. If you happen to have a rifle that has one of their locks, I could use some lock photos showing different variations of the company name. Here's a link to the study: https://korns.org/gunsmiths/WWP-6262025/WWP-6262025.html
