I'm with John. Please save some for me !!
Depending on my mood at the time, I'd have paid at least $20, maybe 40.
I see bodies for a Lionel 150 series and another that I think is not Ives or Lionel - wrong shape cooling grids at corners of the hoods. Problem with those is that it's easier to get bodies than motors. In my awaiting restoration collection now are 13 bodies and only 10 motors of that vintage of Lionel engines.
But the piece de resistance is the three 604 observations.. If all six insets are there then all you need are trucks, couplers, window material, paint and observation platforms to do a good restoration - the hard part is finding observation platforms. Hennings has repros for the 612 - just checked my 612 and 604 and find those railings to have same dimensions and slight difference in the tabs, so they could be used.
Right now I'm restoring the 603-603-604 Red Comet. Dry transfers are available for those cars from J&A and each set can do two observations.
