What you have there depends on the size. If the dimensions are 14"x 10", you have a "Gretsch Renown Junior Parade Snare Drum". If the dimensions are 15"x12" or 16"x12" it's a "Gretsch Renown Economy Parade Snare Drum".
My guess on the date is between 1940 and 1950. IDing the claw style would help with dating the drum. Looks like it's in great shape, it's vintage and collectable. The "Junior" went for around $40.00 and the "Economy" around $50.00. Both Mahogany shells with maple hoops. It's worth at least double that now. I would find an old "period" Gretsch drum key and stick it in the key holder and it will be ready for "The Three Camps"! Good Luck with it.
