[Mauser720]

lowlander -

You have a 1942 9mm Luger made by Mauser.

The "8,82" beneath the barrle near the receiver is the diameter between the lands inside the barrel; i.e., 8.82 mm.

The wooden chip which is missing from the top rear of the left side grip just beneath the safety is what is commonly called "The Million Dollar Chip" since it further reduces the value.

The serially numbered parts which show all appear to be matching. Yes, being plated greatly reduces the value, and it would be of no value to a collector. (in my opinion)

Is that a cartridge in the magazine? Unless you are using it as a home defense piece, I would not store it with cartridges in the magazine as this may weaken the spring.

Hope this helps. It's always nice to have a firearm that has been kept in the family.
