collectorfirearms.net had similar one like this in the past: 4-digit s/n, 2-line address text. Asked $800 something. I viewed that one a few times but missed the gun because I waited too long and someone else took it.
Before long, God may know I am waiting for it (?), another one was offered for sale. Better, coming with holster and two magazines. But auction end time was not very convenient -- 2pm in the afternoon. The winning price was about right, not many crazy people bid in the afternoon. $500 (if you have a good gun for sale, consider your listing time, don't let it end in the 2pm, or worse, 2am
)
Here is the gun. Not in my hands yet. Will arrive soon. I heard Finnish call this thing "Akka Mauser" (Aunt Mauser)
