I have a 7mm Pentax XL for sale. It is a 1.25 in. barrel size EP. It has two end caps and a bolt case (but the eyelens cap is not the original one) There are a few small set-screw marks on the barrel from the previous owner (I have compression adapters). In careful examination before putting it up for sale I noticed some dust on the interior lens surfaces that I have never noticed while observing. It can probably be blown away easily but I don't know the secret of opening these. It is still provides beautiful tack sharp views with 65 degree apparent field of view and perfect eye-relief.
$180 shipped to you in the US.
Thanks for looking, Eric
