Marlin reps who attend the MFCA annual meetings have continually steered clear of any thoughts to having a custom shop. They pretty much said if a run isn't 1,000 guns or more they wont do it.
Davidson's has commissioned several 1,000 gun runs to Marlin, and they have all been good sellers, even getting collectable status. If someone has the finances to have 1,000 guns built, they can do so, but only 1,000 identical guns.
