I understand why you could see anything about constructing any of the bows you look at on that site.
It's a museum located in Columbia, MO. They house the largest collection of archery and archery related items in the world.(I believe I read that as fact somewhere)
The Columbia Area Archery club got to help unpack all of this stuff when it arrived. How very cool do you think that was? I can tell you 1st hand...WAY!!!!!
If you look through the site in its entirety you could be online for awhile.. Some really cool stuff in there for sure.
God bless, Mudd
