I might be able to help you out, if your interested.
I have a pair of virtually new Klein 's with the replaceable gaffs.
I only have the irons though, no pads or ankle staps, I robbed the pads off the Kleins to put on my straight gaff Bucks.
On page ninety one of the current Sherrill catolog is a picture of them.
I only used them to take down a couple of small trees, I didn't feel as comfortable on them as I did my Bucks. I bought them from Sherrill's, they would not exchange them for a pair of Bucks, they have been hanging in my shop ever since. I think I have had them for 6-7 yrs now, the paint is still on them, the gaffs have a little surface rust on them from being in the shop.
I can download a picture later tonight, if you need to see them.
You can have them for $ 50 bucks ( irons only ) plus some shipping, darn things cost me $ 200.
