Dalton adding machine question
Message #1 Posted by David Engle on 8 May 2002, 7:34 a.m.

I picked up a Dalton adding machine this past week. Can anyone tell me about the one I have or point me in the direction to gain more information. All I can tell you is that the Pat. # on the front says 1912 and the number on the small plate on the back is 69541.

Please email me at with any information.

Thanks, David
