Hi
I can't help you with the first one but the second one have a finnish Tikkakoski barrel installed.
Those rebarrelings was awfully common in Sweden and Finland up to the 60th and maybe 70 th as the Lugers was very common competition guns and many guns have had their barrels shoot out.
Another finnish barrel that is common is the one Marked Sako.
It sounds like the gun have a toggle from a 1929 Swiss Luger.
