Isn't there a way to notify the administrators about suspected fraud? Not everybody is lucky enough to have experts in 1860s militaria at their electronic fingertips.
Those sets are absolutely reproduction. Matters of construction are the final nail in the coffin. Even if I were a collector who knew little about Civil War equipment, I would be very suspicious of how complete the sets are. It's been 150 years, and cartridges and caps are still in the containers? The belts are still attached? Little items like a nipple pick is still there? What's the old saying "If something seems too good to be true, it probably isn't." Other than the name on the strap, there's no provenance offered for this remarkable collection. (Not surprising, really. I have 3 just like it in my garage.)
