I would like to stay old school on options... basically a factory or period correct aftermarket heater... want one with good heat and good airflow for defrosting windows... are there hi-speed or 2 speed fan motors that can be upgraded?

the 1950 1 ton presently has a heater with an external air pickup and small vertical flap door next to cab sidewall.. also has a temp control valve on firewall ... were these available in 1950 ... or would this already be an upgraded heater? Looks like the deluxe style heater.

i will put pics on but dont seem to have sucess... any help?
