George is pretty close, it's DutchHowever, I think it's Royal (made in Amsterdam) in stead of Van Der Glas.I get the confusing with Van Der Glas as they kind of copied many features from the Royal snare in those days. But with some small dissimilarities.The hoops are typical for Royal regarding the kind of "squared ear" where the tension rod sits. The slotted tension rods are also typical for Royal, Van Der Glas had slotted ones that were rounded. The snare mechanism has some relief on the side (Royal), that is absent at Van Der Glas snare (see i.e., http://www.vintagedrumforum.com/showthread.php?t=13469 ). However, the snares and there attachment to the snare mechanism parts is more Van Der Glas than Royal; Royal used single snare wires versus Van Der Glas was using the 2 times 12 strands. Last, Royal produced snares of 6.5inch depth that were 99/100 brass, whereas the 10 / 12/ 14 inch deep snares were made of wood. One of the few wooden shallow Royal snares can be found here: http://www.hidehitters.com/snaredrums/snaredrums01.html 3rd from below.My guess would be that this is an Royal snare, that was converted from a deep marching model into a shallow wooden snare. Lugs resemble Beverley.What's the diameter? Royal is known for producing metric sizes. So, be aware that your drum can measure 361 / 363mm in stead of 357mm.
