I bought one of these, a S70 in late 1981 from a firm called Replicaguns in Fulham Palace Road London. They must have bought old stock from the importer when they went bust. They had S70's at £69.95 and B54's as well for about £85. I think they were substandard because I got a refund on mine and went and bought a HW80 for £72 from Streatham Armoury.....

The price of the S70's then went DOWN to £49.95, if you check Airgun World late 81/early 82 you should see their add.

It was a shame because I always wanted a BSF, I remember seeing them for sale at Sussex Armouries shop off the Strand, they had a B54 Match with a beautiful walnut stock, but it was an absolute fortune..
