identify unknown condenser?
It's 24/40 and 10/30, could it be a heat exchanger perhaps?

It's a modification of a Dimroth condenser, with
the ordinary helical coil substituted for by some back and forth tubing. It's from the era before Keck clips were common; it's got the little spring
barbs on the sides of the side joints. My guess is that the glassblower didn't have the right gear (mandrel, or burner setup, or what not) to wind a
proper coil and this was the next best thing.

Given the (small) ground joints on the sides of the cylinder, it looks to me as if it might be part of a vacuum line. Maybe refluxing a solvent
through the large cylidrical body could maintain a temperature in the inner tubing, much like an abderhalden drying pistol.

That was my hit too; a constand temperature maintence device. Pick your boiling liquid and the condesning vapor temperature will be relatively
constant. A lovely apparatus to accomplish a simple task, huh?
