Hello mccracken,
If you think to buy a Mauser Parabellum, I suggest to you to visit my web site where you can have a look at the different Mauser Parabellum models.
www.lugerlp08.com
Concerning the delear and the price, in the link area of the Luger forum you can find the link to Collectors Firearms, Simpson Ltd.
If you look at the Interarms area you can find a few Mauser Parabellum for sale. In this way you can also have an idea about the price.
Do not hesitate to contact me if you need more info about the Mauser Parabellum.
Have fun.
Cheers,
Mauro
