In spite of a couple similarities to the sideplate Lefevers, those Waverly shotguns always seemed pretty crude in comparison to even the lowest grade Lefever. If I saw one on a table at a gun show, I'd barely slow down. I guess imitation is not always the sincerest form of flattery.
Now for a real "ghost of a Lefever" that you wouldn't be embarrassed to be seen with, check out the J.A. Prechtel that was built in Cleveland, Ohio. I recall seeing another J.A. Prechtel SxS that sold on Gunbroker about 15-20 years ago. I'm almost sure it had the later conventional top lever, but wouldn't swear to it. It was also a pretty high grade gun, more ornately engraved than this one, with the stepped or rebated sideplates typical of B Grades and higher. It is said that J.A. Prechtel was an apprentice under Dan Lefever, but I've never heard that any indenture papers or records have been found:
