Both bits of the trigger cost less than 27 Euros, the main trigger as I said the
Pathos at 23.31 Euro and is ideal for a rear trigger, the front one was made up out of 2mm strip brass from B&Q and slodered together to form a big lump with a slot in it for the pushrod pivot, it took Colin about 1 hour to make 2 of them. The pushrod is 3mm brass rod with a 2mm thick pivot piece soldered on the end. I think next year we will get my brother to make us some proper bits out of stainless steel, or even sacrifice the wooden handle in favour of an Alexander handle and forward trigger to simplify the whole set up
