Barrel blank ID

[akajun]

Just picked up a 28” Rimfire blank from an estate
Stainless sendero profile
End is stamped
p348
S. 16
22rf
Written in sharpie is pac nor standard match on the side
But I called pac nor, the lady said they do not put pac nor on the end and she doesn’t know what p348 means
Any idea who made this?

The p348 is the lot number. Stainless 16tw 22 rimfire. Ive seen that stamp style before but i sure cant remember who it was. It was a little manufacturer like maclennon or similar
