Rcat - welcome to the board! It looks like the Museum is in much better condition than when I spent 6 months there in 1972 (OCS). THanks for posting the pictures!
What do YOU like to shoot?
If you think the the museum is in good condition you should see the rest of the base. My son was stating in a brand new house on base, very nice. Alot of construction going on, working on all new housing.
As far as what I like to shoot, I have a 1/3 scale 10 lb Parrot barrel from South Bend Replicas. I have it mounted on a simple sled style mount that I built when I got the barrel 15 years ago. Getting ready to build a No.1 carriage for it. That is how I found this forum, I was researching cannon carriages.
