Heater Box Design - Lame?

Pretty easy to add a valve. You want to know just how tough it was "in the old days?"

I am old enough to remember when Dad did NOT run antifreeze all year round, in ANYTHING. There was a pecking order for it, too. The stuff that came out of the "best" car went into the second vehicle or the tractor

Also I used to have a stack of Ford dealer "propaganda" magazines. These were small thin magazines distributed to the dealers. They may have been "Ford Times" I don't recall.

I remember one article from the mid 30's about how "Dealerships can make extra money by servicing cooling systems spring and fall, and draining and replacing antifreeze AND REMOVING AND INDEXING CAR HEATERS UNTIL NEXT FALL

I am old enough to remember riding in two different Model A's Dad had. One was a pickup made into flatbed (nice little truck!!) and the other a dump. The dump had NOTHING for a heater, and those cabs were DRAFTY!!! The flatbed had an accessory 3rd party deal, a trumped like device, the fan blew air into the "big end" and it fit around the exhaust and "hopefully" piped some warm air into the cab
