wrap is one of the mysteries of vintage drums. there are a few known facts but even a lot of those are unverified. some of them are only known through replicated hearsay or direct comparison of wrap.

there were at least 3 wrap maker's active from the 50's ,into the 70's and if you include oddities such as Trixon and Tromsa's croco wrap, there were 4 at least.

one in the U.S., two in Germany and one in Italy. there likely would have have been one in England( acetate wrap?) and one in Japan as well.

from a logical point of view, it makes no sense for the Japanese to be buying U.S. wrap and then re-exporting finished drums wearing that wrap , back to the U.S. the cost would have been entirely prohibitive. if you look at the 60's Japanese wraps anyway, they do seem a little cheaper and less refined than their American or German counterparts, so it seems pretty clear that there was a maker somewhere in the orient as well. the same material has extensively been used on other musical instruments, signs and in commercial decorating, so there is a bigger market out there than just drums.

the method of mfg. of the cellulose wrap , would be similar everywhere and therefore the ultimate wraps could look similar between makers-----even the same wrap from the same mfg. could change in time or be intentionally changed to custom order, so could mimick someone elses. any wrap company could fit in a custom run eventually, if any other company wanted to pay for it, so if you wanted a wrap featuring King Kong eating a banana while clinging to the empire state building, then you probably could have it. it's just price and quantity.

the other thing is that the name of a wrap is determined by the drummaker using it, so a wrap's name is specific to the name it is catalogued under for a specific mfg. there are lots of examples of the same wrap being used by different mfg. under different names.
