Unclogging Mouot Traps

I had the privilege of recently purchasing a house built in 1926.

I has a Mouot vapor system that is almost entirely original.  It still has the original BOILER (87 years old. amazing) that was converted to gas at some point (1950s?).

Problem is that several of the rads don't heat properly.  At most the first couple vertical units heat (or none), but that's it.

Here's a few facts: The vapostat is set on 2 ounces of pressure.

The return line is vented.

I installed 2 Gorton No. 2 vents on the supply side.

I'm wondering if the Mouot water seal traps (that have no moving parts) have corroded and clogged.  There seems to be no way of taking them apart.  Does anyone know if I can remove them and clean them?  Otherwise, I suppose I'll just remove them and replace them.  Better yet, I'll have my steam guy do it (shout out to Gerry Gill, best steam guy ever)
