Just received some more info on my drum:"Shells were either bent using either a wet or dry process...the wraps were glued on a fabric glued to the shells. Then burlap was stretched around the shell. The burlap had wood on each end..the two wooden sections were clamped together to uniformly squeeze out air...and set up drying. Later the seam was glued down and clamped"The above seems to be what I see regarding the cloth and burlap.Check it out in the photo.Also - it looks like someone has cut down the wrap....probably to help the head fit better. You can also see what appear to be blade marks to the right of the wrap seam joint. As we know, some of the heads fit tight on old Gretsch shells....and this one does. I noticed that the head fits a little better on this end that it does on the other. But asided from what may be 'after market' chopping and cutting...the wrap appears to be factory.
See, These ovens existed in the 40`s, and were steam heated before oil heated later on. Oven heated drums really gotta soak in water or something like a flood to delaminate and this drum shows no signs of water damage to me !i
