Wherle 42A Senior

I recently discovered this Wherle Model 42A under an old porch on a house I was renovating. I plan on restoring it to working condition and could use some direction - wouldn't want to do harm to the stove during the process so any advice would be very much appreciated. I haven't started to disassemble it yet but the stove seems to be in great condition and is complete except for an external pump that it requires. If I could find a pump for it I think the stove would be something I would enjoy using on camping trips. Thanks for your comments in advance.

A bit of back story: When I found the stove it was in an enclosed concrete crawl space that had been sealed up for at least 27 years. It was set up on a wooden crate marked "Popsicle Products Twin Orange" and had child size tea cups, saucers, and plates with it. A few other items that were in very bad condition - croquette set, forks, spoons were also scattered about. Made me wonder how much fun the kids had in their "kitchen".
