I have the smaller version of the Charles Raymond machine that you say might be a prototype for the number one. Mine says Charles Raymond Guelph Ontario on the shuttle race slides on both sides of the needle.. It is a treadle machine which is much smaller than the Number 1 that I own. I have never had much luck finding out more information about it. We assumed that it was made in the original factory in Guelph that burned down in 1875. We are the only collectors I know who have a complete machine on the table with treadle. Can you tell me where you go the information about this machine? I would be happy to send you a photo of the machine. We live not far from Guelph and the machine was from the area. [email protected]
