Help me identify strange keyboard layout

[Dog80]

The first line of letters is the classic QWERTYUIOP, but there's a A with a circle on top after the P.

The second line is the classic ASDFGHJKL and then an O and A with two dots (umlauts?) on top of them.

There are also some other minor differences. For example the minus and plus signs are somwhere on the bottom of the keyboard.

It's either Swedish or Finnish

Finnish worked for me. Thanks!
