Trying to find info on a couple bars

[chilly460]

Discovered a couple bars in the garage that I got awhile back, finally got around to cleaning them up and getting numbers off them. Both are 20"

One is a sprocket nose replaceable nose which is stamped:
215211 S2
21 SSW-50
72 X 3-8
Made in Canada

Other is a laminated sprocket nose bar:
8921
GF558

Any info would be appreciated

The made in Canada one is likely to be a Blount product Carlton, Windsor, Sabre or a bar produced for one of the saw brands Homelite Husky etc appears to take 3/8 x 050 chain with 72 DL's
