bAKER BOILER FINISHED

The Baker boiler.
 Today I finished the pressure vessel. I still need to design a firebox or base to mount it on.
 I finished it without the cleanout system as I went by the drawing I had.
 
A friend sent me the drawing back in 2013. I was unable to find more details on it but finely decided to go ahead as I needed a project to keep busy.
 
There is one measurement on the drawing of twenty-two inches. Using that as a scale the pipe sizes are estimated to be
 
The main drum 4 inch pipe size about 4-1/2”
The out side riser 1-3/4 inches
The bottom two coils 2 inches about 20 feet
The six coils above that 1-1/4  about 200 feet total
The 12 superheated coils one inch of 170 feet
The 6 economizer coils one inch of 85 feet.
The bottom diagonal pipe two inches about 20 inches long
This is just a rough estimate. It would be nice to know if the casing is off a boiler. What the actual pipe sizes are.
 
Attached are a few of the final photos of the pressure vessel and the drawing I went by.
