Karrier Gamecock. Larger model than the Bantam. I always remember the difference because the Gamecock has the radiator filler in the grille - Bantam is on top of the panel, just under the windscreen. Remember the G's grille = Gamecock. Its a pre 1958 model as they had the split windscreen which was roughly level with the top of the doors. Later model single piece windscreens also had a higher roofer cabbed and the single piece windscreen went up higher into the cab - about 2" higher than the top of the doors. Hope this helps
Cheers
