WOW indeed. That sniper rifle M/27 PH aka sniper rifle M/37 rifle is about as rare as World War 2 era sniper rifles can get. Only 250 Physica scopes were made and 150 of those were first issued with M/27 infantry rifles (the remaining 100 scopes were later issued with M/39 military rifles - creating a combination known as sniper rifle M/39 PH). Since during Continuation War (1941 - 1944) most Physica scopes were moved from M/27 rifles to M/39 rifles, the number of M/27 PH sniper rifles was considerably reduced by end of World War 2. Year 1951 only 24 sniper rifles M/27 PH remained in inventory of Finnish Armed Forces.
I think most of the Finnish (=m/39, m/27) snipers are still here. The m/37s are very tough but the m/39-43s change hands from time to time. Search goes on and chances are better than elsewhere in the world.
As much as I crave a Finnish sniper rifle, I'm glad that most stay in Finland where they belong. Us overseas have already bought up large chunks of M39's and others, not to mention the much-envied M28/76's.
