Jim,
the key to keeping your pictures upright is to edit them before uploading to the Parker forum, I generally just adjust the shadow and my pictures are always upright.
I'm interested in your findings, I acquired a Nichols & Lefever 8 gauge hammer gun that was doubling for me while playing around on the 5 stand at the Fall SXS
Now that gets your attention, 3 oz's of lead departing at one time
When cocking my left hammer, there's barely any confirmation of the hammer being cocked, I'm guessing the sear may be worn?
