My first shooter arrived today; need help with unit markings

[Dwight Gruber]

Jan,

I don't know that there is anything uncharacteristic at all--I haven't the experience. I hope to learn whether or not the M, the design and position of the anchor, and the appearance of the numbers are within the realm of authenticity, so I can make the determination myself the next time I see something like this.
