Josh-
I have also been looking for a couple of Imperial loading tools, but I am very much afraid of those offered on eBay. Some of them look exactly like the repros I bought from Sarco . . . . excellent tools, but not authentic Imperial era.
If you have a flatbed scanner you can create very good digital images of loading tools. Scan at 800 - 1200dpi and size to suit after you have the image stored.
The image below was created on my Epson scanner at 1200dpi and sized for the forum afterwards. The titles were added by using Adobe Photoshop.
