Hensoldt Wetzlar scope info wanted

Not my normal kind of scope but am looking for any info regarding a scope I picked up, don't need production figures etc but just a time frame of either pre or post war,

The scope is a Hensoldt Wetzlar Ziel Dialyt x 5, scope No 18982 it has at some time in the past had turret mount rings soldered to the tube these were full circumference, will upload some pics later.

I,ve been after something like this for some time, but its not for a Mauser its a long term project that I want to fit it to, if its a rare or war time scope then will fix the lens 9re cement and move it on unless it is post war then will use it.

Sniper rifle M/28:

Suojeluskunta (Finnish Civil Guard) became interested about scoped rifles about the same time as the Army did. The start of Suojeluskunta sniper rifle development was promising but their selection poor. First Suojeluskunta decided to test rifle scopes with 6.5 mm x 50R calibre Japanese rifles as quality of available (mainly captured Russian) 7.62 mm x 54R ammunition at that time was considered too poor for sniping. Another by-path were six Japanese rifles modified to 7.62 mm x 54R calibre and equipped with Oigee Luxor 6X, Oigee Grom 4X and and Hensoldt Ziel Dialyt 3X rifle scopes. The modified Japanese M/97 and M/05 rifles designed by J.E. Kuusisto were not much of a success. Also the story of Japanese rifles in use of Suojeluskunta was about to come to its end, since it got rid of its Japanese rifles only few years later. In year 1929 the Japanese rifles were set aside and testing new scopes was started with new M/28 rifles. Funding for acquiring 700 scoped sniper rifles had been suggested to Suojeluskunta annual budget already year earlier, but only eleven M/28 sniper rifles were ever acquired. With a hindsight one can note that if Suojeluskunta would have acquired the suggested 700 sniper rifles at that time, it would have completely changed the history of Finnish military sniping. Being series made for testing rifle scope designs, these rifles had large variety of scopes. The scopes used in them included not only earlier Oigee Luxor 6X, Oigee Gnom 4X and and Hensoldt Ziel Dialyt 3X, but also newly acquired Busch Vizardrei 3X, Busch Vizarfunf 4.5X, Hensoldt Ziel Dialyt 5X, Zeiss Zielklein 2.5X and Zeiss Zielmunti 1-4X rifle scopes. Scope mounts for these scopes were manufactured by GECO (Gustav Genschow & Co). Because Finnish Army suffered for chronic shortage of sniper rifles during World War 2 also these few M/28 sniper rifles with their varied scopes were issued for frontline use for Winter War and Continuation War.
