David, I am familiar with the mechanism, I had read Skip's post from years ago, and sorry to hear he passed. This goes back to my original idea that we need to catalog these now before any more knowledge is lost. I have already drawn out the ejectors in CAD as well as the Ejector Guide Block. I would like to get the measurements from a working Ejector Extractor (only need one since they are mirrored)...I believe my right one is close as it works most of the time but would like to verify measurements on a known good one. The flat spring I would also like to get measurements for to verify...looking in the Plans and Specs book which has a picture of all the components, it looks like the spring does not have a square end in the picture so mine maybe close...I have figured out all screws, pins, washer, nut, forend spring ect....
