Up for Sale is the SNAP-ON MT 308JB Compression Gauge Set. I bought this new in the early 1980s when I had my Service Station Business. I sold the business in 1985. This set was not used very much and is in Excellent Clean condition. It has been stored protected in a carton in my garage. It is all there with 6 adapters and extra valves. The original warranty card is still there and the instruction booklet. The front cover of the booklet has some holes in it, not sure how they got there.
