I have a pair of new and un-used Trudesign seacocks for a toilet.
1 x 3/4"
1 x 1.5"
Both have 90 degree elbow fittings for the hoses to attach to. You will just need to buy the skin fittings (which are about £5 each).
£80 for the pair (paid £105), so a reasonable saving. UK shipping £5 or you can collect from Oxford area, or I am often in the Hamble area.
