From Vorisek Vol II
Pittsburgh Fire Arms. 68 5th Ave, Pittsburgh, PA.1860-1885.
1882-1885 they had a hammerless boxlock that was marked Pittsburgh Fire Arms. It also was marked Anson & Deeeley on top. It is possible this was through license with Harrington
& Richardson. This is only gun that had Pittsburgh Fire Arms on it.
Sellers gives the company the same date of operation.
There was a discussion with pictures a few years ago:
