Swamp Donkey, do you happen to have another one of those MK-3 mirrors? I have been looking for one for 3 years! thay were only supplied to the military and are rated one of the best mirrors. 3x5 is a tad big to me, 3x4 is a good size to me. I doubt you will sell it to me since it is in your family for 20 years. Hold onto that, it is a great keepsake!!
