|Seaforth......... Don't understand any of it! Can you clarify what you want me to answer in separate Q's otherwise the answer could take a page! In short, if a telescope is removed from an unnumbered bracket its parentage to THAT rifle is lost because the match is via the cross referenced tele and rifle number. Remove the tele from the bracket and any cross reference is lost. Now imagine the total chaos of 20 T rifles in a big workshop all being totally stripped on a bench and being rebuilt later. Yes, you can match the tele to the rifle from the paperwork. But you cannot match the most important part of the equation......... The bracket and rifle. So, if for any reason you have to remove the tele, you MUST number the bracket.
