Thor,
you can wait to post your list if you wish... but there is another alternative...
you could post your list withOUT attributing names and ownership... just a cut and dried listing that stated gun type and serial number(s) with a photo if you have one available...
Since you are the owner of the data, and photographs... no one could object to you posting them since ownership has not been revealed... kind of like taking a photo of the Leaning Tower of Pisa and publishing it without getting Leonardo Da Vinci's approval
BTW, I have to toss my hat in with those that believe that your mark is not only necessary, but will also be considered your signature and cause for collectability of a particular weapon as time passes... your work is unsurpassed in my experience and I hope you continue to do it for a LONG time.
