These are very vintage Comet kits, from a time even before they came in colour-printed boxes. One is a refrigerator car, almost complete (missing maybe some of the cardstock icebox hatches). The other is an automobile carrier, possibly missing some small parts. I believe these kits were sold without trucks and couplers, but there is one set of sprung metal trucks. The auto car has instructions for a reefer. The instruction sheets are just scale drawings, undated, by Fred Schleinz(?) Ladysmith.
