I have very carefully reviewed the dis-assembly and assembly article, it is a wealth of information. I have attached a photo of the scope for identification, and some closeups of the lens assembly. The rear most lens looks like it is missing some type of threaded ring? I can see what looks like a faint roll over line on the opposite side with a slight amount of solder showing. Is this the side I should remove in order to get the lens out? The innermost lens is perfectly clear, and I am somewhat hesitant to take it apart since it appers to be in very good condition.Attachment 37771Attachment 37772Attachment 37770Attachment 37775Attachment 37773Attachment 37774
