Mark LTim,
I really happy to see that you are undertaking this. I have a George Gibson, number 68, blank backed. I don't collect the different backs but I have a Gimbels large block Adams #1 and in Gimbels italics I have both McInnis #117 (M101-4)and Rousch #146 (both). I know you didn't ask but I also have a Strunk (M101-4) with the Indianapolis Brewing Co. back. Best of luck.
Mark
