Is there a such thing as a BC series or BT series boiler in A.O. Smith boilers.

I'm doing research on a lot of boilers and I'm stuck on identifying a lot of A.O. Smith boilers. Ones that are coming up a lot are ones like BT251, 270, 365, etc. And there is also a plethora of BC670, 420, 399, etc. The main things I'm looking for is somewhere where I can identify the correct labels to give each of these boilers and I also need to see the ratings for each of the boilers. Also what could it mean if a boiler is a BC420 but it's written out as BC420740 or BC420780. Hopefully someone can help me out and send me some literature for one if not both of these models. Thank You :)

    Find an old legacy rep firm or mechanical engineer, in your area.’They tend to keep product binders for generations🧐
