Offered by selection are various power eyepieces for the
Weaver TS-4 and TS-6 Spotting Scopes. As these spotting scopes were made by
Kowa, my understanding is they were identical to the Kowa TS-4 and TS-6, just
relabeled as Weaver. As a result I assume they should also fit the Kowa
labelled models in addition to the Weavers. Although I cant confirm this 100%,
I am 98% sure. If you have a Kowa spotting scope please view the pics with
ruler measurements to help you confirm fitment. 4 of the eyepieces show minor signs of use, mostly minor edgewear, though the 16x 20x also has scuffs. 2 of the 16x 20x show no signs of use. The boxes they are in all show varing degrees of wear as can be seen in the photos. A couple of the original side labels have fallen off, and been replaced with masking tape dentifiers. All of the eyepieces remain in sound useable condition with no lens issues.
These are very difficult to find, so if you have a TS-4 or TS-6 Spotting scope and need either a replacement or additional power eyepiece, here is your opportunity.
The magnification power of the same eyepiece is different depending on the model you use it in. Below are the powers I have available with the Model # beside it:
