Can anyone confirm this as the 1955 D/S listed as either OMM-002 or OMM-003? Got in my change this weekend. Just hoping, I never found one before. I do know that it isn't the one listed in Cherrypickers Guide. Thanks
My reference lists eleven different D/S RPM varieties. Several of them look similar to what you have. If I had to decide between OMM-2, and OMM-3, I'd say it looks more like OMM-3.
Jody: Thanks, that is the one that I thought. It seems to have the diagnostic in the D (of United) but it isn't a high grade, and it's hard to determine.
