Help Identifying A Few Wisconsin Precancels

I am relatively new to precancels (although do have a basic understanding) and can use some help with these. I am trying to determine if these are legitimate or not. I know that generally commemoratives are not precanceled, though there are exceptions which were done at the local post office.

These appear to be precanceled – they are MNH and full gum on the back so I am assuming not post-canceled. They also don't line up well so would assume some type of hand stamp?

However, I am having a tough time identifying the type:

Wausau: The precancel type doesn't match any type identified in the precancel society's town & type catalog. It somewhat resembles a 479 (haven't measured yet) and has a serif font, but the only types listed are sans-serif.

New Lisbon: When I measure this out, it appears to be type 471, however that is a very rare type so I am doubtful it is what I have. It doesn't match other types that I have for new lisbon.

Wisconsin Rapids: Again, doesn't seem to match with any types out of town and type catalog that are associated with Wisconsin Rapids.

Merrill: This is the one that may have a match. Looks like a type 548 from Merrill, but including a picture as reference anyway.

Any help, especially on the first three, are appreciated!

The Merrill is thought to be a PSS-548 that somebody cut up to make single impressions. The other three are well known fakes, probably made by the same schmuck. Fun collectables but they will probably never get listed as valid types.

Thanks, very helpful!
