Hi all

Had these old Japanese 'Citation' porro's for ages and only just noticed there's different JB numbers on each side of the hinge!! |^|

Maybe one side was made at Itabashi Kogaku Kikai Seisakujo Inc.,Tokyo (JB22) and the other (JB32) was made at the Miyako Seiki Co. Ltd |:$||:$|



Anyone have any idea what happened?, Maybe a mis stamp |8.|

One makes the body, the other the finished product. I think you'll find that the JB 22 is really JE 22. :cat:
