Sorry I don't think I'm going to help much. I've had a good look over your photo's and compared them to my Raleigh Rapide and I'm still not sure, whilst there's a lot that looks the same there's bits that are not.
Lugs, look the same
Rear stays, look the same
Dropouts, look the same
Rear brake bridge, looks the same
Top tube cable guides, look the same
Rear mech cable stop, looks the same
bottle cage bosses, look the same
Forks, look the same
Colour, the white looks the same, and that is quite a distinctive colour.
But
No down tube lever bosses (they could have been taken off I suppose), the silver grey paint (could have been applied after the bosses were removed) and I'm still not sure about the top of the seat lug and possibly where the stays meet the seat lug but this could be just the angle of the photo as in the last photo (hard to tell with such a small photo) it does look a lot closer.
