The lighter in the game is a modified IMCO 4700 lighter imho. It‘s the only model that has the handle attached to the round part. But it‘s squashed to the proportions of a 6700 junior. The sleeve design doesn‘t exist as well like that and I talked to an IMCO collector. So it‘s either the 6700 junior with a different handle or a 4700 with different proportions.

I chose the 4700 and streched the sticker. The sleeve is shorter as well, but what you gonna do? It‘s at least time period accurate and I suspect avoiding copyright issues as well.
