The polident cleaned them up pretty good but I put them back in the soaking box and put water and a little bleach and let them soak again this time they came out much better. after drying I made 2washers extra thin out of brass and supper glued them to the hinge end of the scales on the inside. when this drys I'll install the blade with another very thin washer between the blade and the washer I glued. I've never done this before but am hoping with the two brass washers one stable the other moveable that the one glued to the scales will give added support and help against cracking and the loose one will act like a bearing so when it tightens it still will move without torquing the scales . anyway the brass washers are so thin that I don't believe you will be able to tell theres two per side.
