In reading the latest commercial from Cornell Publications -
http://www.cornellpubs.com/old-guns/item_desc.php?item_id=2624
I see a reproduction 1924 catalog for Kirkwood Bros. The "link" shows the cover and describes the contents of this repro catalog.
Following info on the front cover - Kirkwood Bros. Inc., Est 1874, 23 Elm Street, Boston 8, Mass.
I suspect this would be the same "Kirkwood" that Dr. Bill McPhail would be familiar with.
Usual statement - I have no connection with Cornell Pubs, other than being their occasional customer.
This info offered FWIW - and a very Happy & Healthy New Year to all.
