JayMuzquiz - about your uncle's machine
The picture you posted is a Singer 66-1 in an Open Side cabinet. I can't tell from the pictures if it is an embossed cabinet or the plain style. I have both - along with two 66-1 machines. If you have the serial number of the machines (near the base of the pillar) that can be used to find the year the machine was made. The decal is officially "Scroll" but it's common name is "Red Eye". It was used between 1902 and 1923. ISMACS.net is the site I get a lot of information from for the older machines. Do you have any of the attachments or a manual with this machine? They can be a bit harder to get. And to the cabinet, does the door have the table support leg and the removable locking drawer and the drawer insert? Often they end up missing on these cabinets. Sorry about the format of this post - my Enter key won't work ( First time posting here from my work computer, and "work" does not appear to like this site LOL!!)
