Hi thomas65G (I assume your name is Thomas but it does not show in your profile)
Dave (dadipentak) forwarded your request to me. I have his old SMC 1000mm F8 and it is intact and working. I would be happy to assist you. I will look at your photos and my lens and will get back to you. From my first look at you pictures it looks like you could easily make the parts.
I am packing fro a trip and am leaving in a few days and will not be back until the 10th of October and may not have time before I go but I will try.
Have a good one!
Murray
