A Little ID Help Would Be Appreciated

[John Liles]

Good afternoon All,
I had occasion to look at a couple of guns this weekend that belonged to a good friend who passed away last year. His wife asked if I might be able to give her some idea of what he had, and she'll decide whether or not to keep them in the family or let them go.
She had a couple of Elsies, an Ithaca, and a 20 gauge Parker in pretty darn nice condition. Can someone tell me what the book says about VH (I think) 150756?
As some of you know I'm pretty well versed on the LC Smith gun, but mostly what I know about Parkers so far is that I like to hang out with the guys that shoot them!
Thanks for any insight you can share.
John
