That place has an interesting history. I have a friend who purchased 25, 50 gallon drums of "junk" from an auction in the mid 50's of Bannerman's estate. That "junk" has slowly been sold over the last 25 years and that is how he made his living. He also purchased several civil war cannons, a Colt Navy gatling gun, dozens of rifles, and all sorts of other military stuff from Bannermans. They say inside those walls are Civil War musket barrels that were used to strengen the morter. An interesting place for sure.
