Were you able to resist?
Ha Ha!
Yes, I already have 2 primo 1390131s, although neither was New-In-Box.
I have an immaculate original in completely stock condition, and one totally "tricked out" bolt-modded, white latex blanket, 2010 Unicomp springs, XT key caps, internally padded (but not floss-modded) with beige Orihalcon USB cable.
The only other standard-size Model M I have left is my 1991 beige label 1391401, completely stock, the first Model M I owned and still just as good as any of the others.
