Thank you for the link, much interesting reading there!.... I can find no model number on the saw anyplace! , it is a 20” and the S/N tag says it’s built by Rockwell. Looking through your link, it appears Rockwell took over in the mid 1950’s and I see no saw larger than a 16”. Also the list doesn’t go beyond 1960 so I would assume it was built post 1960. I did replace the tires on it yesterday and had sourced replacements from a vendor on EBay who matched my wheel measurements with a Rockwell model. I’m not sure when Rockwell dropped the Walker Turner name, but perhaps this saw as a prototype design for Rockwell or some like situation!.... It’s an awsome saw and I’d like to keep it that way, LOL...
It was a significant departure from the previous heavy cast iron Crescent designs so I suspect it was a Rockwell or
Delta design rather than originating from Crescent. The first reference to the Delta 28-350 20" saw seems to appear
in the above instructions (1947) and it shows up in the 1948 Delta-Milwaukee Industrial Machine Tools - Catalog A48:
Thank you!, the first link is my saw! I did find info on 20” Rockwell saws and it appears a model 28-356, 28-365 and 28-366 are the same saw!, and I found a manual for those on eBay!.... Many thanks for the help
