The only camera I have available is a cell phone which does not take good pics.
Mine looks exactly like yours, no dash except for the "M". I bought it new in 1986. Its only had about 1/2 dz. rounds thru it by me plus what the factory did when the "M" was stamped in it.
I usually take it with me when I go camping or travel packing it in luggage or a box with other stuff. Its like new, I have the original box, receipt and all other papers and 2 speed loaders.
