estate sale find. old case is marked sherzer augsburg. horn looks to be silver plated. no markings except 1-2-3 on the valves and a serial number 566872. one person replied it to be a "stencil" horn made in the 40s 50s and possible by sherzer. the case as we all know may not be original to the horn. anyway....please have a look and take a guess or any info is appreciated. thx!!!
