Armstrong 9pc 3/8” Deep 12pt SAE Socket Set 15-326A

[Dzmax77]

I bought this NOS USA made Armstrong 9pc deep socket set off of Cripes for a decent price. If you’re looking for some SAE deep sockets, there’s still some left at Cripes. However, I really want the Metric version of these. If the SAE set has a 15-326A model number, what would the metric be? It doesn’t have to be Armstrong; I think they made these sockets for Craftsman and other brands and don’t care which one its.
Thanks in advance!

There's the larger Armstrong 18pc 44-350 set (6-23mm no skips). A more direct equivalent metric set for your current SAE set would be something like a smaller 13pc 10mm-22mm set with no skips. Depending on the year they were made, there might be only stamped markings or stamped and laser etched size markings on the sockets.

Other than Craftsman, Kobalt is another brand that shared the same socket manufacturer for a time. Kobalt USA sockets (post USA Williams but pre-Taiwan) are getting harder to find as NOS listings, but when found they often still sell for good prices.
