Kevin, I can give you basic information, even a "shooter" Artillery is worth $500 - $600 in bad shape and I have seen re-blued ones go for close to a $1,000. Like many things, condition is everything and if not original, (i.e. non-matching parts, reblue, the value drops dramatically), but that said, an artillery should have an 8 inch barrel and they usually go from $1,200 and up, these are very rough guesses and if the following is supplied, a not as rough guess can occur:
Can you tell us any other 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.
What serial number is on the gun? To include any letters next to or under the serial number?
Can you provide pictures, to include side, top, etc?
And any provenance, bring back papers, memorabilia, etc., can bring the price up.
