Just a quick update. I got the ok to post off the pistol to the chap it is going to and it has now arrived.
I included a rough (very rough) set of wooden grips that were bonded to the frame of an earlier Junior I bought the other year. I also sent the old mainspring so he can attempt to re temper it if he wants---------although it was shooting fine with the new spring I fitted. I also widened the rearsight notch a little to make it a bit easier for old eyes to focus. I've suggested a bit of paint of a colour of choice on the foresight as well.
