(OP)
Historic building that has seen multiple renovations in it's 120+ year life, doing a preliminary structural evaluation for the owner as the structure is very unique (3rd floor is actually suspended from large timber trusses via 1.75" diameter metal rods!).
Anyway, found this framing stamp on one of the floor framing joists added during what I would guess to be a 1930-1950 renovation where the replaced the 2nd and 3rd floor framing. Trying to decipher it but not coming up with anything. Any idea what SEL MERCH and 131 WPA translate to? Best picture I could get, sorry (borescope into the floor). I believe that the grading agency abreviation says MILA or NILA.
Location is northern Maine.

It appears that SEL MERCH = select merchantable, and it is roughly equivalent to a "NO. 2 and Better" grade.
Any guess on what 131 WPA means?

Where I am on the west coast, it's WWPA or "Western Woods Product Administration". So this could be a general stamp as opposed to a regional one.
