Finnish Lahti questions

[raydeon]

im eyeing on a couple of Lahti. One is with Serial number 47xx, all matching, series III. However, it's missing the boxed SA marking under the VKT marking on the top of its slide. Does it mean that the slide has been replaced at some point of its service life? if so, who replaced it and why isnt it SA marked? or is it one of those "made with rejected parts" and the army didnt accept it thus the lack of the boxed SA?

The second one is on Simpsons, serial number 0001. I have zero clue how serial number 0001 even exists. Can any pros give me some education here?

Thanks!

Sorry I don't have any helpful info for you but I did own a Lahti a number of years ago(about 12 or 13 years). Mine was marked as a Danish police gun, if I remember right. It was a heavy pistol but a great shooter. I got it at a gun show for about $350. Right after I traded it off prices started going up on them.
I never see them around here anymore. Iwish I had never traded mine off.
