help have no heat but have hot water

I have an hb smith boiler from ??1943?? with hot water. My problem is the burner fires up to heat the water but will not fire up when I turn on the thermostat. Brand new thermostat honeywell ct87a 3 wires red white blue (series 20 wiring I think) also brand new rebuilt honeywell ??switching relay maybe?? L147A4k-03 The original aquastat L428BX1 (2 huge mercury bulbs inside) B&G circulator from the early 1940's. The problem is I looked everywhere on the web these things are so old its like they never even existed. I called honeywell thinking I wired the L147 box wrong they're more than useless. Everything says 115v for the current. The only thing I found was the 1943 boiler schemactic by searching the patent no. on the U.S. patent website but I couldn't understand it. Last year I ran out of oil but I primed it my self and assume I did it right because it comes on for hot water so other than that I'm lost can anyone help? The switching relay?? has a thermostat transformer and another transformer water maybe? 3 terminals 1,2,&3 I have black to 1 white to 2 and yellow to 3 it also has 2 r terminals 2 w terminals and 1 b terminal for my thermostat wires coming in and also going out to the oil burner. I tested my thermostat and there is power going to it. So ??? help me please...Thanks

I'm not sure what to tell you except you are giving very specific info about some very old & obsolete controls. What you really need is probably to send that setup packing and get a new system in there.
You probably didn't want to hear that, but then nobody usually does.
