Can anyone identify this bike?

[cjlink]

I bought this old bike today, and I could use some help in identifing its id. Someone has already repainted the frame and added a sticker to head tube. They also swapped out the handle bars and stem with newer parts. The bike has an old Bendix brake. The top tube is 22" in length and the seat post tube is 19". On the back side of the head tube, there is a little metal tab about an inch above the joint with the bottom tube.

Thanks

Murray built Spaceliner. Mid 60s to early 70s. Might be chrome under the paint.

SHould be numbers stamped on the rear dropout. Post those, and we can usually tell if Murray built it for Sears, Gamble's, Western Auto, etc. -Adam

I was looking for the MOS stamp, but all that located was the following number on the rear dropout:
