I have one just like this:https://www.ebay.com/itm/Vintage-Cl...244-21033-Sears-Penske-NICE/283446222036
A very popular unit, more useful than Snap on.
Mine is mint in the original box, all inner packing, original manual (48 pages) and accessories. Used probably 4 times.
Pics and details if interested. $65 + shipping from 92020.
The large 7" meter (IIRC made by Simpson) is nice. When Sears made good stuff in the USA 1970's.
And an Actron L-204 inductive timing light, mint like this:https://www.ebay.com/itm/actron-l-204-timing-light/352837388589?
$20, can combine with analyzer. Made in USA - real chrome metal, not plastic.
