2 boilers in the 75 year old house. I know they are old, would like to be more specific if I could. I haven’t been able to find anything online.

Galaxy Cast Iron boilers
Model: G-225 P
Serial: 070059, 070060

Is the “70” in the serial the year?

There’s also some insulation inside the units to the left and right of the burners that may be asbestos?? pics atached.

From the pictures, the units did not look that old (could be misleading).
The following website has some info (not sure if this helps):
