Default Wisconsin THD

So I found a thd in my dad's shed. I have a couple questions. Does this have a oil pump in it. And what is this line running from oil pan to the front cover is that what lubricates the gears in that.

All Wisconsin THD's have a piston style oil pump. You should drain the oil out and remove the oil pan and clean out the last 50+ years of sludge. The oil pump screens are known to get all clogged up from dirty sludgy oil, and the check balls are known to get all gummed up. You will destroy the engine in no time if the oil pump is gummed up. Use a good grade of SAE 30 motor oil in your engine. The hose coming out of the crankcase is clearly a drain of some kind. It must have been situated in a piece of machinery where the oil drain was not easily accessible. It looks like there is just a bolt jammed into the end of the hose with a clamp acting as a valve. I would either remove it all and plug up the oil pan, or put an appropriate ball valve in.

Clearly not a drain because oil is returned back into that front cover

That makes absolutely no sense. The oil in the pan is under zero pressure. That line would never have any oil in it. I would remove it entirely. The only oil line on a THD under pressure goes between the block and the governor housing.
