Nitro, I was able to get in. You have to fill a small registration form which is not very user friendly.

There is no estimate for the .333 Jeffery but the starting bid is 240 EUR. The auction hasn't yet started according to the website.

I'm trying to understand the origin of the rifle. It appears to me to be an Oberndorf pre-WW1 Mauser Type B which was chambered to .333 Jeffery by the English trade, but I thought Rigby had sole rights in Britain to the Mauser action prior to 1912.
