A leather trunk to restore

I have worked on several old steamer trunks over the years, but never one like this. This is unusual in that it is made of leather with ornate embossing. but it was in horrible condition! All of the leather was dry rotted, all the stitching was gone, and the whole right side end panel was detached. I almost said "It's too far gone to attempt repairing."
