UPDATE: This was up for auction last year in 2018 and 2019. Starting price dropped to $1600 with the auction scheduled for Friday, June 18th (Today).
I’m surprised to see no bow holders. Looks like the dash plate in a long, single one, and I see no column shift. I’d say this was a mid 1946 or later photo.
