MTSI seemed to specialise in Lionel-like flat cars with loads, particularly military loads.
The three producers Chicago Line, Geller Toy Trains and MTSI appear interconnected, although to what extent is unknown. Boxes are very similar, cars stamped MTSI are marked Chicago Line etc. Dennis Heavrin of Chicago Line and Bob Geller of MTSI were both involved in the production of the TCA Postwar Lionel Reproduction Handbook Guide, c2000. Bob Geller and MTSI are the same business?
