We have a problem with a T Model Bsa standard (1930s) Basically, the trigger is firing of its own accord: as soon as it is cocked, it releases itself and will not hold.

I have given it to Protek to repair but they are in difficulty. They report:

“I have tried 3 pistons now, 3 cocking links and 2 trigger mechanisms. Your rifle will only work with a different trigger block (regardless of trigger components) so the problem is with the existing trigger block - but not sure how to sort it out or even why it won't work. It nearly does but not quite. I look at the rifle and get depressed and frustrated about it. Your trigger block will not work on the 2 other rifles I have tried it on either.” Unquote.

A new trigger block cannot be used because of the different levels of finish. If the mechanism could be revolved one further turn, it is expected the mechanism would operate but this would mean that the holes for the screws became inoperative and out of line.

3 different sears have been tried but none of them worked in this trigger block. But the sear from this rifle worked in another rifle. It is possible the rifle’s trigger block is making the mechanism bind up – one possible theory.
We have tried different pistons so we can discount this.

Can anyone help?! Protek would like to receive suggestions - as would I!

Many thanks!
