If you would like to treat your eyes, and get some nice pictures of Y Blocks, check out Mecum 57 Heaven auction consignment list.  There is a museum in Branson, MO , 57 Heaven, that is going out of business.  The museum, had only 57 cars.  There are F & E code 57's in the consignment list.  The auction is October 24th.  IF I were a megabuck guy, I'd be there :-)
