Kurt welcome to the forum!
If it is NOT a reblue, it is worth more than a shooter by probably $700 or $800 dollars (much more going by what Herbert stated). Of course it all depends on condition, condition, condition.
You can learn a lot by reading previous posts in the Early section, or doing a search for 1906 commercial, under the search part of the forum.
All the 1906 models have a grip safety I believe.
I don't know, I thought most 1906's were 7.65mm?
Can you tell us any others markings on the gun?
Proofs? (see on your left under tech information if you came through
www.lugerforum.com) Tell us what and where proofs and markings are located.
There are forms in this section, where you can print out and then write down pertinent information.
Can you provide pictures, to include side, top, etc?
