Was surprised to see we have the same last names.

: I just acquired an "american Bosch Radio" model 5, from an estate sale. I am having difficulty finding info on this radio? would appreciate any info anyone might have. comes in a case that looks like it might be for a portable sewing machine? when opened wooden radio lifts out. also at this estate sale i picked up approximately 150 very old volume and on/off switches. if anyone is looking for a particular one and i have it just pay postage, thanks, alfred leal
