I basically agree with fnb25. If there is no agreement between the seller and the dealer, then you are using your detective skills and knowledge to identify the seller. In this case an inquiry to the seller would not be out of order.

On the other hand, you state the dealer has been totally honest and fair with you. If there is an agreement in place, I suggest you give him the benefit of your knowledge and experience with these type guns, which he apparently does not have. Advise him of your interest along with your expertise and perhaps a deal will result.
