Sorry the pictures are so crappy they looked good on the phone. As for the six button did they or did they not used during the Span am war or the Philippine expedition i also have a khaki I believe 1904 tunic it has no grommet holes in the collar and has appropriate collar insignia for the time. I have seen some of these with Span Am campaign hats listed as Span Am war but I've never seen any pictures and all Khaki uniforms I've seen have the stand collars and coloured epaulettes. There is allot of stuff from this time period i have with it very confusing as i only collect WWI before this.

Okay so its not 1880's period? how can you tell the difference?  

Welcome to the forum. Your extensive collection must be very interesting. I hope to get to know it little by little. Regards.
