It's a Gen III, model 10616.
Even though, Kahles has a limited lifetime warranty it only applies to the optical system. All other parts warranted for 10 years. Past ten years of use, all repairs are handled on a case by case basis.
Here is a copy of the Kahles Warranty (the warranty is transferrable):
Thank you for purchasing this instrument and welcome to the world of KAHLES. Since our founding in 1898, the KAHLES community has been committed to providing an ownership experience, which includes our legendary service that is second to none. We sincerely believe that our optics are the best in the world and put them through rigorous tests to ensure that the name you trust is built to the highest standards. But in the unlikely event that you discover a problem in defects in workmanship or materials, we will gladly examine the instrument. KAHLES offers a
lifetime warranty on the optical system for products purchased by US residents from an authorized North American dealer. Once examined, if it is determined that the optical system is defective we will repair or replace the instrument or defective part. KAHLES warrants
all other parts of the instrument for ten years from the date of purchase against defects in materials or workman- ship, subject to normal use. All electronic components are warranted for two years against defects in materials and workmanship, subject to normal use, from the date of purchase. All non-optical products (i.e. accessories, tripods etc.) are warranted for one year from date of purchase. This warranty is void if damage results from unauthorized repairs, accident, alteration, misuse, abuse, neglect, fire, flood or other acts of God.
I would also mention the red indicator for the second rotation of elevation turret. Very cool feature!
As for the sunshade, it's available for a purchase as a separate accessory (
