Dang,
That is a good bit of rust through.
What is that box? Is this the heater box from the burner?
The rust and holes on to the right of the picture are quite evident, but you could fix this. Metal plus welding does wonders.
Do you have any pictures of the burner and configuration?
The tub is in awesome shape. I am wondering if the rust ate through from all the years of sitting....who knows where.
I think with a little macho engineering....you can get it running without any leaks.
I do have to agree the caulking of the suds window is a little odd.
I also agree with you....this machine was used more than they said in the ad on eBay. I bet they quit using it when the leaks arrived. But then...who knows?
I do think it could be a great machine with a little TLC.
It is beautiful!
