IR Scopes - Hi/Low Serial Numbers to Date-Feb 2020

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   The following is a summary of the serial numbers we have collected to date. These serial numbers have been confirmed thru photographs and/or communication.

We have info on several dozen scopes that have had the name plates removed and several dozen scopes the photos do not show the serial number clearly.

Please help us build on this information as original documents providing exact quantities manufactured have so far been elusive. Instruction on how to help are posted in the Announcement regarding this research project at the top of this thread.

Thanks

Jim
