Another "Need help" with ID

Here is another mystery stock, any idea what it goes to?

Not sure but looks like it could be either an Ithaca 37 or a High Standard...

Thanks!
Looks to be off a JC Higgins 66.

That looks like a model 1897 Winchester stock to me..................

I'd say High Standard FliteKing ... but that slot on the side is different. That might be something their Supermatic had, I don't know as I'm not that familiar with them. Unlike most semiauto shotgun designs, the High Standard Supermatic didn't have a bolt return spring/spring tube in the stock.
