I have been tasked to make some lens caps for a 2" unertl scope. All the information that I had to go with was the outside diameter of the bells and the inside diameter of the threaded areas. I gave it a shot and missed on both ends. Do any of you have a 2" unertl with caps that you could give me accurate measurements over the threads of the caps? The information would be greatly appreciated.
Thanks in advance

Thank you Rabb, The size you gave me is pretty close to my caluclations, but my guess came out just a bit oversize. What you gave me for the rear is way off from what I had been given. Your numbers make a lot more sense. I am waiting to hear back with a little more information from the guy I sent the caps to to try to figure out where the mistake was made on the rear cover.
Again, thank you very much for the info, I really do appreciate your time to answer this for me.
