Goo, I perfectly understand and I wish you all the best in your pursuit. The two books I mentioned have the best pictures that are published. You may try to contact Patrick Hornberger to see if he has some pictures that are not published that he might share. I like this rifle very much and think it to be one of the very best carved rifles that Haines did. I did not set out to do a bench copy of the rifle and only shared my rifle because you share a common interest with me on this rifle. I have seen the rifle in person when it was on display at the Reading Museum. The museum would not allow any photography, It is quite fascinating, to the point that I almost got thrown out of the museum because I stepped on on the pedestal of the display to get a better look without thinking and was immediately collared by the museum security. They did let me stay but was warned pretty good about the displays.
Again, good luck
