Blue Point / Blue Points Long handle single end tappet wrenches
Blue Points Long handle tappet wrenches show up in the 8/29 cat. Three regular models. LT16, LT18, LT20. Also three Special Dodge Tappet wrenches, one being a TSE1218. There is a TSE20 shown below, so they were probably made pre 29. Sometimes in the 30's the name was changed to Blue Point. It seems that Blue Point Tappet wrenches were made until sometimes in the 1950's. Several different model numbers. LT, TSE, XL, CT were some. There were also some specials with the model numbers like Sxxxx.
