Wisconsin BKN engine info wanted

[sunstonecer]

I am looking to try to find the year of manufacture on a Wisconsin BKN engine. From what I have heard they started making the engine in 1955 but I do not now how to tell the year of my unit. The tag on the engine is a little worn but here are the numbers:
BKN 152551 5738105

Thanks for looking

I incorrectly spelled single-cylinder in the pole above but cannot edit it to the correct spelling

1955 was the year and replaced the akn and abn for greater horsepower. I have a manual in pdf if needed
