DIANA G34 .22 CALIBRE - MADE IN ENGLAND - STAMPED 6-62

Hello Gents. Try as I might, I cannot find anything anywhere about this Diana rifle. Can anybody give me any idea as to its value? The action is tight; it fires with accuracy, the blueing is in an all-over good condition; the stock has some scuff marks but these have only be caused by usage.
Thank you in anticipation.
