Looks like it's for acetylene air brazing.

You should be able to tell by the LH connection.

I thought it was for connecting to a rockgas type cylinder like on a barbie.
The connector tells all!

There should be a torch to control the flame .

The long bit on the pipe end, I think is missing some bits.
The other torches are std propane torches.
Commonly used for heating only/ burning paint off (with a wide blade shield fitted) & soldering large items etc.
That specific hose & torch combo would need to be connected to a regulator

Ah, that could be it. There are adjustable regulators that go on a gas bottle.

This was all found in dad's workshop, so trying to figure out what it is.

The regulators needed for this are SPECIFIC for that type of torch.
THey are NOT the std type Oxy/acet gauge & regulator combo

black or blue hose is typically oxygen, orange for lpg maroon or red acetylene.
the two tips look like gas air tips lpg usually are quite large ends to get sufficient heat.
hoses with left threads are for fuel gases
