Baseboard heating element fitting

Can anyone identify this fitting?  It's cast bronze, reduces from 3/4" copper to 1/2".  The long taper and the pins on the side make me wonder if it's something other than a cast tapered reducer.

    Doubtful...

    The pins are probably just a part of the casting process that didn't get cleaned off in the sand tumbler. If it were something like a balance valve, there'd be a packing gland and a machined shaft where the pins are located.

    My vote is that it is a combination expansion-reducing joint. I bet the pin is a part of a length limiting system.
