Need a lot better pictures of tool to help. Often differences in tension mechanism on upper wheel, blade guides, and casting numbers on frame that delivers a band saw true identity?
The covers are reminiscent of Davis & Wells, but frame is not same. Frame has Walker clues.
It s hard to tell more from pics.
Can check VintageMachinery.org and see if find similar band saw.
Try putting this: site:www.vintagemachinery.org bandsaw into
http://DuckDuckGo.com or your favorite image search tool.
As much I prefer LumberJocks for woodworking, OWWM.org forums as best place to discuss old tools.
Can join and ask the old tool experts if they recognize it?
Just note they only allow US or EU made machine discussions. Chinesium tool discussions are banned.
Well that's pretty arrogant of them. Aisan tools are getting old now too. Not all are HF level junk.
Best Luck.
