Thanks Carmillus

... yeah that 72 is special
Thanks Ken!! As you said Rogers Bone was probably the favored scales at the time - probably even a selling point so as you allude to how many really had Rogers Bone... I do think though Ken and it would be hard to obtain records but I would think some business record keeping docs in storage would have the info - if and where they exist is anybody's guess.... I can be wrong... maybe folks from current or old cutlery companies may have a clue about the old day record keeping and where it went after the companies dissolved... hopefully not the trash
So to that point and as I mentioned above I went back to the old American Cutlers Journal (1922-) - actually a great resource for alot of ads from many cutleries (Empire, Miller Bros, NYK, etc etc etc) - But my point is I found a few of the different scale or cover companies for bone and stag in addition to Rodgers (CT) which had an ad - the first is The Salisbury Cutlery Handle Co (Salisbury CT - actually near Holley Lakeville but not far (maybe 45-60 minutes - not in those days) from Waterbury area (Naugatuck, Northfield, Waterville etc)... and the other from Sheffield England (sorry thought it was CT unless I didn't find it yet) Ridal & Co, LTD....
Fortunately and unfortunately - it is free on google books to download the American Cutler Journal but I can't cut and paste the ads nor print them (at least on my MAC but should try PC) so:
Here are the 3 bone companies I found to date and I am essentially copying by text on a word doc their printed ads (so each indentation is basically the next line of ad):
The Rogers Manufacturing Company ad (note: no mention of bone in name of company):
- Bone Coverings
- Plain or Stag
- Supplied to many leading Pocket Knife and Table Cutlery Compnaies
- The Rogers Bone Manufacturing Compnay
- Rockfall, CT
The Salisbury Cutlery Handle Co ad:
- Established 1884
- The Salisbury Cutlery Handle Co
- For 37 years Salisbury Handles and Scales have been used by Leading Cutlery Plants
- Office & Works
- Salisbury CONN USA
Ridal & Co, LTD ad:
- Genuine Stag Horn
- Specialty of Pocket Knife Coverings
- Universal Horn Works
- West St Sheffield, Eng.
So there are a few - not sure how many others I will find as I go through the journals (I don't have them all - whatever is on google books).....
