This looks like an interesting museum. Looks like they have some uniforms of the early Philippine Constabulary during the Commonwealth period. I did once visit a museum in Camp Crame but it was then the PC museum. It was dark (minimal lighting not well maintained) and the exhibits were not as organized as the ones in pictured in this article. I remembered seeing a lot of firearms (mostly captured or surrendered). I recall seeing a couple of WWII German MG-34s minus the receiver covers. That was about 15 years ago.
