Local CL pickup. What did I get?

[RCain]

I picked this up today in trade for a MTB frame I had exactly $0.00 invested in.
He threw the Murray in for free.
Any Ideas what it is? He said the skip tooth chainwheel (pictured) was on the bike when he got it, along with the rear hub.

Thanks,
R.

Its Murray built, maybe Jc Higgins badged?

Reminds me of my Murray built Firestone. Same sprocket also. Good score. Either way, I'm pretty sure it's a Murray built frame. Is there an outline of where the badge was?

 

[RCain]

No outline of a badge, just the two rivets. (Marked with arrows.)
Any idea of what year(s) it could be?
I changed out the wheels and mocked it up with a few different bars, kinda getting a feel for it, I'm really starting to like it. Probably a different crank and chainwheel too. Going to put it together tomorrow and ride it. Eventually I'll re-lace the rear hub and put the skip tooth drive back on.
