From the little I can see, it looks a single-speed version of an LTD-3. I've never heard of one, but I'd guess it's a Raleigh LTD. It's a cheap version of the Sports.

I can tell it's not a Sports because it has plain Endrick rims; Sports has fancier (but heavier) Raleigh-profile rims (sometimes called "Westrick"), pump pegs, leather saddle, and other features to bump up the price. And I've never seen a single speed Sports.
I wouldn't rule out the possibility that this is an LTD-3 that has been downgraded to a single speed, but that would be an odd thing for anyone to do.
Do I count 32 spokes front, 40 rear? If so, the wheels are presumably original and it's from the early 70's.
