I've had a couple of old Grenfell Mission (Labrador) wooden letter openers hand-painted with figures in parka driving dogs sleds, and have seen a few other varieties as well, and this puffin is so similar in manner I am nearly certain it is Grenfell Mission as well.  What a charmer of a puffin, and what a charmer of a letter opener, to keep on one's desk, or perhaps to stick like a post into a bowl full of pretty rocks and pebbles. C. 1920s-30s I believe.

7 1/16” long and in good condition, with light wear, minor paint loss and a little uneveness to the blade edge near the tip.
