M. Hanson bow?

[Fishers]

I bought a used R/D longbow from Lonnie's table in Kalamazoo this morning. It's in almost-new condition and looks great, if a little plain, and it's a sweet shooter. One side says "M. Hanson 09" and the other says "071709." The lower limb says 60" 54@28". It has no other markings at all, and I can't find out anything about it online. Just wondering if anyone knows anything about this bowyer. Thanks.
