Vintage 60s 70's Sears Tach and Dwell Meter auto gm service street rat hot rod ?

Description

Here is a Sears tach and dwell meter that has been in my basement for decades. Never used it, seems to be in alright shape, the styrofoam box is rough, it is dirty from sitting around, could use a good cleaning, not sure how old it is, 60's to 70's is a guess. I some how through the decades ended up with around half a dozen of these little guys, I never even got around to trying this one, it has been sitting in a box. Selling off a 30 year accumulation of car parts, so check my other listings, opening bid usually wins, so dont be shy. If you have any questions, feel free to ask, selling as is with no returns, since it is a 50 year old untested used tool, shipping will be 16 dollars in the US 48, thank you for looking and have wonderful day.
