UK Tropical DPM buttons

I found a lovely pair of British Tropical DPM, the one with the mustard color buttons...that is if it actually had all the buttons. It's missing four buttons, one from the fly one from the right leg pocket, one from the left leg pocket and one from a belt loop. In fact its missing the sizing tab buttons as well so I can't even steal them from the waist band to at least fix a couple of the buttons. So one short sob story later I'm looking for 4 or more buttons to fix these up.

Sorry for the quality of the pic its a random internet picture that might clarify the buttons I'm looking for if my description is too vague:

Sorted!
