no idea....

I have messed with 7-1/2" gauge stuff. Live steam, propane fired, coal fired, gasoline/hydraulic diesels, electrics....
This one is odd.

First of all, a brass boiler is NOT a good idea.
Seller claims for a 7-1/2" gauge loco...yet shipping is twelve bucks.

Then the size:

"it measures 5 3/4" x 3 1/4"."

Sounds like a #1 gauge loco...still....not brass! Tubes, yes, even copper...but the pressure vessel?
#1 gauge you'd get away with it for a while....and the resulting explosion would be small.
But some 7-1/2" units have boilers 4 feet long (Mikado) or 10 feet long (saw a Big Boy once) and a foot in diameter.
