Re: I need approx size 12" diameter x 48" length Boiler horizontal expansion tank
It just needs to be drained and recharged. Your relief valve release is most likely from a waterlogged expansion tank.
Get a competent hydronics pro in there to do that, and check your relief valve, boiler feed and the boiler itself to make sure everything is operating properly and safely.
Have them show you how to properly drain/recharge the tank.

So would an AquaSmart 7610B or HydroStat 3200+.
Re: need WHITE-RODGERS TYPE 842 RELAY-HOTWATER CONTROL,
there are many controls that can replace that. if they can't replace that, they don't know what they are doing.

A Honeywell Resideo L8148E,J would work. Is it a 3/4" well?

Re: 1895 Detroit Home - Single Pipe Steam Unknown Condition - Initial Inspection
I would get a properly plumbed and working boiler in there rather early on, that way you can see if there are system problems you need to fix before you start fixing the plaster so you won't have to fix it twice if you need to get to something. You will also need heat to keep the new finish materials stable once you repair things.

Re: Most reliable heating system for a home unattended for up to 3 months in winter.
My vote is to make it easy to winterize. There's nothing that can run unattended with 100% certainty it will work.
Instead of draining the heating system, fill it with glycol. Then it's just a matter of getting the water out of the pipes and getting antifreeze into all traps and appliances. If you blow the pipes out with compressed air it's easier. Do a blow-out, and as you go, if you ever need a tool, think about a way to change the plumbing so next time you won't need a tool.
Re: Need new boiler
what type of heat emitters, radiators or fin tube?
Rust around the flue connection could indicate it has been running to low of a temperature. Or short cycling due to over sizing. This can also lead to dirty combustion chambers

Re: Steam Boiler Gauge Always Not Working
the water shouldn't exit the boiler
it looks like there is oil on the water as @STEAM DOCTOR alluded to which will cause surging, it probably needs to be skimmed.
