This is an interesting Scandinavian Importing pan. The company was incorporated in Maine, but located in Boston (near where the great Molasses Disaster occurred.)
It is considered Griswold made from the pattern number. It is identical in size to the Andresen pans. Could have been contracted through Andresen, or just a reuse of the pattern by Griswold. The quality of the markings makes me think it is later than the Andresen products, but again, conjecture.
No markings on top, 2992 under the handle, and Scandinavian Importing Co, in raised letters, on the bottom. Better lettering than the Andresen products.
I'm sure this is far more than you ever wanted, but it is stuff I've wanted to document for a while. Usually this is not on the public side, but there is far more on the WAGS side with things that I'm sure will interest many.
