Snap-on Tach/dwell machine

[locolobo]

I know you guys might be tired of me tryin to give away "junk" but here I go again.
I have an ancient Snap-on Tach/dwell machine. I got it back in the 70's and it was used then, so I don't know how old it is. Worked the last time I used it but when was that? I dunno! Don't have anything to hook it up to, not even any spark plug wires to test the tach. In fair shape otherwise Thinkin maybe a curiosity for someone who collects old car stuff?
Otherwise I'll throw it away. In Brazoria county. 979-583-3394.

I am guessing this is one of the small box dwell meters?
When I was in school many years ago, they had a distributor machine, that you could check the amount of advance, both mechanical and vacuum. Then you could set the dwell. To optimize dwell, instead of using a feeler gauge to set the point gap. I used to use that machine to set up my distributor for my 69 Mach. Dwell meters still have purpose, along with tachs.
