the differential loop is just a loop of pipe connected to a fancy casting. you can make it with pipe and tees and ells, you just don't need it on a boiler with a burner you can control.

Is that a prehistoric boiler-mate?

is that an old taco sidearm?

I have no clue what it is yet. It’s a heat exchanger is all I’ve got…I know it’s killer though, some kind of dhw heating unit

probably a sidearm water heater, it was piped in to the boiler and heated the water by gravity circulation. ones similar to that were some of taco's early products in say the 30's and 40's

no but i have seen versions of this diagram. you can make this happen with a little thought and a number of fittings and nipples

That Excelso is just what you thought- a side-arm water heater. Looking forward to more pics.
