leonAlthough I am just a type collector I will be glad to help in any way I can.  I think you and I are 2 of the most die hard "back" collectors out here.  I can tell you that I am aware of 5 Red Cross backs, of which 4 have been known for a long time.  I understand, from a reliable source, that there is a Red Cross Lowdermilk....but I have never seen it.....Let us know what we can do....I will also try to coerce Tbob and some others into helping.....good luck and let us know.....ps...how are those M101-4/5 backs coming along?
