The frame looks too crudely finished to be an English-made Raleigh product. That style of graphic is a knock-off of the 1960s-era Raleigh export models. I've never heard of Raleighs being sold under this name or with this kind of lower level finish. It's absolutely true they had budget-level 3-speed bikes, but the roughly pinched-off seat stays, the head tube formation (it's hard to tell exactly how it's formed from these pictures, but I agree something about it looks off), bottom bracket parts (they're roughly shaped like Heron heads but are also not well stamped), and maybe the front fork blade ends (they looked to be pinched rather than cut and brazed). The fenders look to be mounted using the older style screw/plate mount rather than the single-screw wire loop style. It looks as if the insides of the fenders are painted with red primer still - almost like they didn't finish them?
I wonder if this might be a knock-off made in Asia somewhere. There's a possibility it's a foreign Raleigh subsidiary product as well, but it looks pretty roughly built to be a Nottingham product. But everything about this bike is made to "seem like" a Raleigh, but a lot of stuff seems off from an actual Raleigh product. If I had to guess at it, I'd say it's a Raleigh-look-alike type lower-end bike. At least that's how I see it.
