These earlier pistons were prone to wear from the contact of the cocking arm to the rear of the slot in the piston, had that happened or has it been serviced to the extent that a replacement piston was fitted ?. I suppose there is little consequence to the answer, just that this seems "odd" in the normal context of the guns history.
