Check out the British Bayonet Frog sheath at Major Surplus... well worth the $2.50 for the set of two.
Ahh, you got one of those.
Glad I could help you find them(if it was me), its wired how I see stuff on surplus sites and can remember it like that but I cant remember trig. <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
How does it work, are they good?
