The two Tell 3 pistols in the upcoming Stroud Auction (see https://www.the-saleroom.com/en-gb/a...6-ac8d00dd830c
and https://www.the-saleroom.com/en-gb/a...6-ac8d00dd8417 ) are a real puzzle. One has a calibre of 6mm and the other 61/3 mm, both being clearly marked as such on their barrels. All adverts seen for the Tell 3 indicate that it was only ever sold in 4.5mm (.177) calibre.

Why would two non-standard calibre guns show up together like this?
What would be the point of such large calibres, considering that this is a small and relatively low power pistol? I think the Tell 3 would struggle with .22 pellets.

6mm smacks of 6mm plastic BB's, popular with softair. Surely someone didn't convert a Tell 3 to a softair equivalent?.


Does anyone have any ideas about what might be going on here?

Cheers,
John
