In the description of a vehicle ad, people may list the mileage of the vehicle with a "K" at the end of it. The "K" would represent 'thousand.' So, in your case, 151K would mean that the vehicle has 151,000 miles on it.
The mossberg model 151K was made from 1950-1951.

The Model 151k was produced 1950-51. The average value for the model in good condition is approximately $100-$150. It is one of my favorite guns to shoot. Very accurate.
It is available in both, but the v6 has a very popular problem with engine sludge buildup, even after only 30k miles on the engine. I am not aware of engine problems with the v4. I own a v4 with 151k miles and still original engine and transmission and running like it was brand new.
It was only made for two years- 1950 and 1951.
No exact production numbers avaialble that I know of, but they would have not been extremely high- that rifle was only made for 2 yrs. (I have two of them- for a hunting grade of rifle they are VERY accurate)
The Mossberg Model 151-K was made for two years only: 1950 and 1951.
