Endicott magazines are pretty much all the same. That was the whole point: Standard design. What's in them now, however, varies by their standard of maintenance. I've found a complete deer carcass in a magazine of Battery James Many at Fort Washington in Maryland, and an alert and pugnacious rattlesnake in Battery Van Swearingen at Fort Pickens in Pensacola, Florida...but never have I come across such a treasure as...Andrew Jackson's desk chair!!
