have a look at
I have 6 of these, brand new and in the packet - surlpus to needs, they are hammar type and have used same all year, and no probs, they are a good size, and all bits on are stainless.
Integral harness with ring, and fitted for crotch straps, but they are not with them -- but could order them for you if you want.
retail of them is about £90 each, but you could have them for cost which was £59 + postage - expensive i know, but they are the hammar type,
expire in 2008 i think, so loads of life in them..
Email me if you are interested.
