I googled it until I found the pic, had a few minutes of down time I needed to flush my brain from work lol. There's a bunch of them on google images.
The one was a hill build along on here by John Sweka, and Ray had a similar response to him as he did me about the jig LOL!

Pretty sweet build along btw. I had to put my building on hold, I'm headed down close to Rays neck of the woods. Originally thought I'd hunt, instead I'm cranking flies and plan on doing some late season trout fishing, should be fun! Lots of fly fishing history started in the area and I gobble the history right up! Sure wish the collectors were cheaper on the fishing side than they are on the bowhunting side LOL!
