I picked up some items at the Hamburg, PA show last Sunday:
6464-525 M&StL Boxcar and 6802 LL flat with girders to complete a 1958 Super O GP9 set for the dealer I repair for. He has the other cars, the GP in OB and the set box.
A chrome Marx two light tower. I'm trying to replace the black towers on my layout with the harder to find chrome ones. I've got 6 or 7 now.
Many parts. The two shops I service for continue to keep me very busy.
