For those of you that don't know, the old GJ's were built with very high quality/heavy duty parts. The feed pipes were made of brass or bronze. The augers were made of a special stainless steel alloy. The rings in the pot are designed to rotate the combustion air to promote spiral flow. When they put one of these together they wanted it to go for at least 30 years before anything wore out. Pretty difficult to find anything like that today.

I took the gearbox apart to go thru it and couldn't believe how strong built they were compared to the others I've rebuilt. There is just not a weak point in my opinion. Everything is simple and rugged.
