Identify this old brass tube lug snare

[djd2]

I have had this drum sitting around for a while. I need too put it back together and get it sold. I think it might be a duplex. The shell is very heavy has strip hoops with clips and tube lugs all nickle plated. The bearing edges are folded over and sealed. The throw off mounts with 2 bolts on the horizontal. The throw off lever is marked duplex.

I think it's a Duplex copy of the Ludwig 2 piece shell snare,even to the snare beds formed by pressing.Even Premier over here had a go at the soldered bearing edges.Clifford Della Porter[Premier]told his Dad gave that up as it was to costly.I have never seen such a Duplex inside before but have pictures of Duplex snares like this,the Strainer looks to be the original.Dion
