[C1] Engine Block number
Carefully remove the paint from the pad. Do not use any scraping or sanding to do this use paint remover . Then take pictures .
I will ask the seller to do this and I will get updated pictures. Thanks

Typically you expect those stamped characters to be in-line as characters were held in a gang stamp (holder).
HOWEVER, NCRS Technical Information Manual for 1955-56 does state that some 1956 Corvette stamp pad did have individually stamped characters.
So, I would not necessarily discount this car.
As recommended by silver837, get a photo of paintless stamp pad. Evidence of original broach marks, would help sort this out.

I don't know if image below is of an original pad - would need to examine in person. However, NCRS Technical Information Manual for 1956-57 does state: "Some original engine blocks appear to have been stamped individually." (emphasis mine)
I agree, typically you expect to see these stamp pads in a 5-1-1-5 pattern just as your example shows. Five characters in a gang stamp, then an individual stamp, then another individual stamp, and finally a gang stamp of five characters - 5-1-1-5. NCRS Tech Manual details this 5-1-1-5 pattern as typical, so I believe they do mean individual stamps are possible.
Just saying, other possibilities. Seems like owner is not cooperating, so perhaps moot point.
