The Pardini looks to be in good nick and would be well worth repairing since, as you say, it is not working.
It is a 10m match pistol with single stroke cocking action and probably dates from the 1980's/ 90's. I have never owned one of these but it was a popular match pistol before the advent of pcp's.

I have a Haenel model l DRP similar to the mod ll but I think your mod ll is in fact a mod ll-E variant with the chequered and shaped grip - the mod ll had a much plainer grip. A nice example worth restoring and dating from the 1930's probably.

Hope this helps.
