WANTED: Edison Standard Model D gear parts!!!

[flashpanblue]

Hello,
I was recently contacted by a fellow who is very enthusiastic about restoring an Edison Standard model D that belonged to his Grandfather. It is missing two gears from the top cluster. They are the larger double speed changing gear and pull knob and the middle gear and spacer washer. see the photos for a clearer picture. The last photo is from one of my machines showing what it should look like. I would really like to help this fellow get his family machine up and running. If anyone can sell me the missing parts at a fair price It would be appreciated.
thanks
Pete
