Jeff, the linkages are some old Detail Master pieces that I've had for years. I have to improvise the placement and the "look" of where I want them to be for some semblance of realism. Thanks for asking!
I believe the second link is the company that I bought mine from. Most of the time I only need the first lens. If I have both of them on, it's literally like looking through a microscope..............they are THAT strong!
Hope this helps!
Glad to see you back Bill & sorry for your loss. I myself haven't built in over a year but that was because I finally built myself a full size lowrider and spent the year at shows and cruises. Thanks for posting the links to the magnifiers, I have been wearing glasses since right after Christmas last year when an eye exam discovered I have an astigmatism in one eye, and I just order the second set listed as its now uncomfortable to wear the headband magnifiers with glasses
