I sold it to Baz.
I must persuade him to let me have it back one day!

You may have trouble finding one.

I got it from a Trader at Bisley a few years ago.
Surrey guns or similar name?
They had a few left from a kids horse riding and shooting sport.

I seem to recall it was sold in a Hammerli Box so there may be a Walther/Umarex connection.
