A fascinating piece ? depending on what the original factory hoops were this is either a Haskell Harr Model or a Contest Model marching tenor drum, made in 1963. The Harr is shown below. The only difference between the Harr and Contest was the hoops ? Harr had COB rim shots whereas the Contest had wood hoops and claws, like the bass drum shown in the picture. Other than the non-Slingerland hoops on your drum everything looks fine. As Rich points out, drums over 16 inches in diameter got 2 seams. Yours are in the correct location for a 1963 marching tenor, and they appear nice, flat and normal.
Slingerland did make a 12x17 marching tenor, but had discontinued the size as a regular offering well before your drum was made. So this was a special order, the making of which was very common for the very-accommodating Slingerland. The biggest issue in filling this order would have been molding the odd 17-inch shell size. Check the shell - it is likely an earlier Slingerland mahogany shell ? made by bending pre-formed plywood, as opposed to the later practice of molding the shell plies individually in a former. The earlier pre-1957 bent shell has the tucked ply profile shown in the first picture on my shell page:

The original factory hoops for your drum were possibly wood ? solid maple ? which was easy to custom make in this odd size in 1963. That would make this a 1963 Contest Model marching tenor. It is also very possible, however, that Slingerland used an old 17-inch single flanged hoop they would have had NOS in the factory. A custom 17-inch triple-flanged rim shot COB hoop would have made this guy a Harr model. The length of the tension rods on your drum look short for a Contest Model, but as with the easily swapped hoops, tension rods are easily swapped as well.
Slingerland sold its heads as a separate line, and the 17-inch Slingerland Weather All plastic head on your drum was a standard offering in 1963.
You have quite a unique drum ? it is definitely a collectible, so compliments to you on not drilling the shell. There are many other non-invasive mounting options.
Very cool!
