Rob, you are so kind in answering my questions. I'm confused as to why Wilton left their casting free from C.O.O on their 1740's, 1750's and some 1760's all thru the later 70's & 80's and just left a sticker on the side stating that their main office was in Palatine Il. Your mention of Wilton's C-Series as being top notch, and you feel their Tradesman is next in line? Is their something about the Wilton machinist series you know that we don't?
Thanks for your time.

The reason the names were no longer cast in the sides of the Tradesman vises is because of private brand customers, The cost of pouring separate castings for those customers would have added a lot of cost in inventory. So the vises began having the cavity on the side so that more than one brand could use the same castings and then have a label put into it and other paint options. I believe if a product is made in the USA, it does not have to be marked made in USA for sale in the US. I'm positive that the castings for the Tradesman vises were never made in the Far East. Where they are made in the last couple years, I have no knowledge of, but I assume still USA. It was very easy for China to make grey iron castings, but pouring Ductile Iron was not and still not easy for China to do.
Wilton Machinist vises are also great vises, but they do not have pipe jaws and the height from the slide bar to the jaws is not as high as the other series. The Combination vises have the most mass at the front and back castings and their pipe jaws are much better than those on the Tradesman line. If you want big capacity, the Combination series vises fit the bill as they, have bigger height between the jaws and the slide bar and larger openings.
The Machinist and Combinations vises use steel jaws, Tradesman vises use powdered metal jaws. While the powdered metal aren't bad the steel jaws are better. Same difference on the pipe jaws.
The Machinist vises are probably stronger than the Tradesman Vises, but for the average car mechanic etc the Tradesman is a really nice vise. I have one 1760 and a 1755 for my own use and I could have had any I wanted, but for the size and features they work well. If your working on trucks and large items a C-1 or C-2 would be better. The C-3 is really big as I recall about 150Lbs, so you need to do some series work.
Wilton also had or may still have an 8"' Machinist vise. Sometimes people would call and order the biggest vise Wilton had, that would be the 800S. I would have customer service call the companies back if they were ordered as most people do not realize how big a 248 Lb vise is. Many people were shocked when they 800S vises would show up as they were quite a big hunk of metal and probably half of them would get shipped back because they were so big.
All three series use the same Ductile Iron in their castings, so it's just mass and features that make the difference.
