The pulley configuration is definitely like Delta as are some of the parts but I have never seen a Delta that looked like that one. I have 1938 24" Delta and it is significantly different, yours is not just a size smaller. Up until about that time I also believe Delta used raised letters for their name. Curious.
What size is it? 15", 16", 18"?
I wonder if it could be an old Duro?
