Your concern is valid. I'm not an expecrt on these old stoves but odds are high yours may look like this. Scroll down there are lots of pics.

An item I would have checked for sure is the step down gas regulator. It has a rubber diagram inside it. It can be replaced I'm fairly sure and it may well be an 11" WC step down to 10" WC like the new ones are. I would have a pressure drop leak test done on the rest of it just so you know it is all good. If you have a local LP gas guy, they can test these it is a standard test. Or an RV dealer
I tried to find a manual and no luck. Here is the serivce manual for all series. Page 12 talks about the cross reference in part number from Wedgwood to Atwood.

But... our files section has a 1983 Wedgewood manual.
