You could buy a diana 34 in .20 around 1998-2000, I know because I have one

You'd have to check for sure, but I think UK made Webley's had a few models with the .20 option.
There was also the Turk built Webley Valuemax that came in .20. I know, I have 4 of them.
Daystate used to. Pretty sure Air Force still has at least one and don't forget for a minute about the Theoben's.
zrman already mentioned the D34, although a special run of 30 rifles was done around 2005-2006. I know because I have #15 of those 30 made.
