Not seeing the photos.
Load your photos to Photobucket. To the right of your photo there is a share links. Click on the IMG and that will copy your picture. Then paste it to the IAA Subject box.
To view photos on the forum, they must be hosted somewhere, such as being “hotlinked” from an existing website photo, or by the user posting the photos to their own online photo hosting account, such as Photobucket. Once on a website, the link can be copied and then pasted in a message here, and then you just highlight the link after it is posted in the forum message and click on the “IMG” button to have it appear as a photo in the forum message.
Tim, the one on the left is an early long cased version of the .44 Webley that was made by UMC with an inside lubricated bullet and a Hobbs’ patent primer. It was misidentified as “10.4 mm Montenegrin No. 4” in the first volume of “Manual of Pistol and Revolver Cartridges” by Erlmeier and Brandt.
The one at right is a British Boxer cased .430 Long for Rifles made by Eley Bros.
