My Lionel #1045 Flagman took a beating back in the 1940's when my brother and I were kids.  I just found my old Lionel train set along with this Lionel accessory that was wrapped up Detroit newspapers, The Detroit Times, dated December 1954, packed away in my basement!  That was a long time ago and now I would like to get that old train set out and working for our great grandsons to enjoy like my brother and I did years ago. The 1045 Flagman that is made from plastic, is broken from its metal stand, opened up exposing the right arm with a metal shaft and weight.  All electrics are missing.  I would like to know what these were so I can replace them.  I suspect a solenoid or some such thing that I could make could work.  Any ideas or best yet, a photo of what was inside of the Flagman.  I have everything else in the base including the 1045C tract connector.  My brother would be proud!  Thanks guys, Karl
