Dengu is actually a Pachimon originally created for a mazagine project.

The first link is completely broken/inaccessible, a description of a listing on Mercari which is essentially Ebay isn't exactly a credible source. I checked the Wayback Machine and the first link was archived either.
Obviously, your last revert is not constructive at all. AND you also removed the description based on the tweet by Karasawa. And the first link is NOT broken, at least to me. I still can access it without any problems.
I've been wondering to contact my fellow Japanese toku fans to ask if anyone has creditable sources. If you have problems with the sources, then you should hide the section as the first step rather than removing the whole part.
Apparently, the term "Pachimon" has been widely used for variety of original kaiju, and those NOT by Yokopuro and Yamapro have been confused with Pachimon vintages and have been treated as Pachimon on numerous occasions by fans. For example, Gamaron and Wanigon.
So, I briefly expanded the introduction of Pachimon article to explain this. The amount of such original kaiju being treated as (or being confused with) Pachimon should be worth mentioning.
For the first one. I see, yeah it would have been better to hide it instead of full on remove it. Also, since you were able to access the first link, maybe you can take a screenshot of it and upload it here so I could see?
As for the second one, thanks for telling me that. Also, from what I could find, the term "Pachimon" has been used as a slang term to refer to knockoffs in general rather than just vintage 70s kaiju/toku/mecha bootlegs? I have thought of updating the opening paragraph to include that information in the past but wasn't completely sure on that.
Does this work? There may be system issues with these links. https://auctions.yahoo.co.jp/jp/auction/f1222585733
Actually, the term "Pachimon", also as "Pacchimon" and "Battamon", is very widely used, not only for this topic. The name of this Bachimon vintage is simply based on this Japanese term anyway.
In these case, including King Rampus and Dengu, "Pachimon Kaiju" and "Pachi Kaiju" have also been used.
