Hi, Simos! Yeah, I suspect that that someone mismatched the box and soldiers. Those are "English Grenadiers 1900", which were set 210 in 1952. I based this on the info in Richard O'Brien's "Collecting Toy Soldiers" 4th edition, "Collecting Foreign-Made Toy Soldiers". There's a photo of the officer and grenadier on page 310. The box is for the Gardes de la Reine.
The article, written by K. Warren Mitchell, notes that until about 1950, CBG's label didn't indicate the set's catalog number, but rather, a size code, and the number of pieces in the box. He gives an example of "214/12 Imperial Guard", where 214 is CBG's size, corresponding to 55mm, and 12 is the number of figures in that box. If that's consistent, then 361 indicates CBG's size for the 3 figures that were issued in that box. Unfortunately, Warren didn't include a table that listed CBG's codes and their corresponding sizes.
Regardless, the figures you have are definitely English grenadiers. That's evident to us, even without finding CBG's catalog reference for them.
When the book was published back in 1997, O'Brien listed $14 apiece, for figures in very good condition. I wouldn't venture a guess whether we could estimate higher, 24 years later, but looking at some auctions on eBay and at Ray Haradin's Old Toy Soldier auctions would give a better idea of what similar figures are going for today.
Hope that helps!
Prosit!
