Leitz, Leicaflex SL2 and Dust in Viewfinder

I just sent off a mint condition Leitz, Leicaflex SL2 for a CLA. The camera looks as if it was never used, and the technician said that the lubrication was as "dry as a bone" Everything was cleaned, lubed and adjusted. 

The camera came back working perfectly, but there were a few, annoying specks of dust in the viewfinder (on the focusing screen)  I found out that the grey spots correlated to dust on the outside of the focusing screen (inside the mirror box) and the black looking spots means that the dust/dirt is on the inside of the focusing screen.

I sent the camera back for the technician to take care of something else (and to also clean out the dust/dirt) which he did, but I guess in shipping the camera, some more spots surfaced.

It obviously won't affect the images in any way. I know that these 40+ year-old analog cameras are hardly dust sealed, but is this common?

Thanks, Brad

I'd have to say that yes, it's quite common in bodies from the '60s and '70s.   Almost every camera I own from that era (and earlier...  some 25 Konica, Yashica, Pentax, Leicaflex, and Nikon bodies) has some sort of dust or debris in the finders.
