I'm hoping maybe Perry or James or John K. will stop by.
My Orr Painter was disassembled and put through the lye bath.
Word of caution...
If disassembling these baby stoves, have your camera firmly in hand.
Remove all removable parts, and then take careful photos of from all angles and document each step.
The number of parts will be numerous, and may surprise you,,, which makes reassembly a challenge!!
My O/P needs a few 'adjustments' around the oven portion, and will be challenging... I am heeding the warnings I have been given..

If there is oxidation, my opinion is to get after that. I would use Evaporust.
Some of our folks have really done some neat restorations... e.g. Perry's Dolly's Favorite and GF Filley, up to and including replating of pieces.
