Here are one pair of large finder scope mounts and 1 small finder scope mount. They are used and were from Lafayette in about 1966. They are Japanese. The single small mount will accommodate a finder scope with a MAX diameter of about 1 1/4". It is about 3" from the base to the centerline. It had been used on a 2" diameter main telescope tube.
The pair of mounts are about 3 1/2" from the centerline of the finder tube to the top of the radius of the base. A finder scope of about 1 1/2" to about 1 3/4 " can be accommodated. The curve on the base of the mounts fits about 3" dia tube. The mounts are cast metal, the felt lined rings are hard plastic.
Of course, you can modify these mounts to fit just what you may need.
Please study the photos and ask any questions. I try to be honest in my descriptions. Shipping will be $5.00 USPS 1st class package. I will ship international, but please check with me for actual pricing first.
