I had a guy give me a Philco 37-61, and I've been looking for a case for it. It seems there are more of the 37-60 cases out there. Looking at some pictures, it appears that the radius at the top of the case is slightly different - but it could just be the angle that the picture was taken.
Does anyone know if there is a difference between the two? Seems like the 61 has 3 bands, where the 60 has 2, so the dial window (name escapes me) might be different. Thanks for any guidance / thoughts -
