Snap on double-box wrench 5/8 3/4

[blackhawk-tech]

Gents,
At a local yard sale a picked up what appears to be an old off-set boxed end wrench from Snap on; it has seen better days so I plan on cleaning it up and polish it.
The part number is XS2024US PAt3273430; as I want to collect it the entire set, anybody knows if there is a part set number or do I have to randomly find them?
Thanks for the help.

They came in sets and individually. There's probably a date code on that wrench. Single number. You can consult the Snap-on thread (see Index in Stickie) or the Collecting Snap-on website, linked here, which is outstanding, including a date code chart and every catalog from the 20's to the 90's.

Nice wrenches. An all time classic design. I prefer the older ones to the current, due to the rounded shape.

Yes, clean it up, but don’t go too mad! A light clean with some very fine wire wool and a rust preventative oil will probably be fine.

In case you haven’t worked out the numbering system,

‘X’ is a box end wrench
‘S’ the short version, and
‘20’ & ‘24’ are the wrench sizes in 1/32’s, so you can work out the numbers for the others you need!

Originally a Blue Point numbering system. Still used today!

Here's my two cents. I bought most of them in the 1950s and 1960s but went crazy on EBay a few years ago and now have one of every wrench in that series made in the period.
