I stumbled upon this site when researching an antique sewing machine that I have. From what I have gathered it is a National SM Co. two spool almost identical to the one found in this thread

I have pictures of it if can figure out how to post them, but mine looks to be in better condition than the one in the previous thread.
Any information on what exactly I have would be greatly appreciated, and I have always found boards like this to be the best place to get honest opinions.
Thanks in advance
