Here is the latest group shot of my large multi's. The five in the back row are from my new year's day "rescue" and, with the exception of a couple minor chips here and there, are in good shape. If I understand the system, I believe they are M-4325's, three for sure are Ohio Brass and the two burgundy ones I will need your help on. The four in front have been with me since I was 14 or so (4420, 4325, and the hefty Thomas whose number I am unsure). The M-3490 was purchased from Elton Gish a couple years back (before the drought put a dent in my collecting) and continues to be one of my favorite.
