Good find, Mike! I found an identical set on ebay about 3 years ago for $87 delivered, also in excellent condition after I cleaned the goop off with some solvent. I would easily pay $100+ for them today. Apparently, Starrett makes good stuff. Who knew?

Great find! Over the last 3-4 years I've found the smallest 3 of those at various yard/garage /flea markets for about $25 total---not in that condition, but serviceable after cleaning the crud off. I continue the search. Sammy
