Keilwerth/H-Couf
Can anyone give me any info on this sax www.ebay.com/itm/231318890562 it says it may be a Keilweth stencil but I cant find any info on it online, the only info is on Bueschers, Martins and Conns that made Velvetone saxes, but no Keilwerth, plus, this looks too modern to be any of the other 3...
