May be wrong, but except roll length, 120 & 122 are the same dimensions....
Yes, unfortunately, 122 format uses a 1" wider film stock than 120.
Those adapters mentioned above (and here:
https://filmphotographystore.com/products/adapter-122-to-120-film-adapter) will allow widely available 120 film to be used in the camera, although the 'short side' of the rectangular images will be clipped about 1/2" top, 1/2" bottom. Instead of the 3-1/4" x 5-1/2" 'postcard' format image, you'll end up with images that are somewhat panoramic... 2-1/4" x 5-1/2". You'll get approx. 7 shots total on the roll and might have difficulty advancing the film accurately.
The good news is that you can get 120 film processed. I am pretty sure no one processes 122 film, so you'd have to find the necessary darkroom kit to process it yourself, which might only be practical with black & white film. I suspect it would be difficult or impossible to find film spools in 122 sizing, as needed for processing.
If you go the route of shooting adapted 120 film and having it processed, be sure to specify the lab NOT cut the film . With 120 it may not do so anyway. But, if they do, any sort of automated film cutter is used, it probably wouldn't recognize the unusual format and you might end up with images sliced into pieces! Auto printing also may be a problem, due to the odd format.
Beautiful example of that camera, though.... well worth giving it a shot!
You mention the camera was "new in box".... The box actually might be just as valuable as the camera! You probably already know, having the box with it will likely enhance the camera's value considerably, so you should keep the box, as well as any and all packaging that was inside it.
Whoops! Just saw that the link I included was already posted in another response. Well, at least you've got lots of help!
