Good Ideas, as for P-3 Parts I only have 1 E-handle, still have a few things to work out with it. However I do need a little help Identifying the box I use regularly. It was passed down to me by a gentleman whose late brother was a competition shooter. The only stipulation was I had to pass it on when I no longer did competition shooting I could not sell it, only pass it on. There are no labels or tags on it, there is one that appears to have had writing on it but it has long since worn away. I estimate the age at 40+. Any help identifying this would be appreciated, thank you all in advance.
