I recently posted a couple of videos about classic Tinsley telescopes.
The smaller scope in this picture is a Tinsley 3 inch. Video at https://www.youtube.com/watch?v=JtQRkQebbKk . I had to repair the mount as shown in the video but otherwise the scope is all original.
The larger scope in the picture is a Tinsley 4 inch refractor. It is nearly a complete superficial restoration. The basic scope, focuser and objective are all original, as is the wonderful mount. All the paint is new and the finder is a replica I made. Please watch the video at https://www.youtube.com/watch?v=dmz_Wg58iVw .
Here are some shots of making the replica finder rings on the 4 inch for those interested in machining.
