The museum here at Ft Sam Houston is pretty good. Lots of frontier era military gear, uniforms, lots of guns. The only examples of a Benet Mercier MG and a M1904 Maxim MG I have ever seen. But it is housed in an old building, and everything does appear antiquated. They have a huge collection of old photographs of about everything ever associated with Fort Sam. I have copied some of them, used them in making some historical presentations about the Army during the Indian wars and the campaign against Pancho Villa. I haven't been there in about 15 years so I don't know what it looks like now.
