ErikD - sorry to correct you but Prechtl makes complete rifles for Sigarms with "Mauser Original" name on them... look at his internet site:

see the "mauser original" signs...

You don`t buy "real" Mauser rifles they are Prechtl products under different brand - nothing to worry through Prechtl rifles are of highest quality...

Jabalihunter - Johannsen uses Prechtl mauser actions, Walther Lothar barrels and Recknagel components like open sights, scope mounts... Good components but the rifles craftsmanship, fit and finish are more comparable to "lesser" rifles like Heym than to true Master Gunsmiths... Options list is also limited, and you must pay lots of money for anything "non-standard" that is if you convince him to make that what you want... While Ritterbusch, Hartmann&Wiess and Theo Jung will make a totally bespoke gun with virtually any option thay you may want to have in your rifle... if you have the money that is

I have a friend in Germany who is a firearms journalist and he says that in the last few years the two Gunmakers i have mentioned above (KHR and TJ) really steped up in qualitty and now make a comparable product to Hartmann und Wiess... So look for new K.H.Ritterbusch and Theo Jung Mausers...
