Had one a lot like that for a few years, until I went for a second restoration and found the fork steerer bent, so got rid. It was an old post office bike, and had brackets on the head tube for the carrier and twin top tubes for strength. I was told by the bloke I bought it off that the bolts on the bottom bracket put it pre-1930’s, but I’m not convinced. The way the seat stays bolt to the top of the seat tube is very like Pashley’s so it could be one of them.
It was bloody brilliant, 3 speed Sturmey Archer gears and once up to speed just bombed along due to the mega wheel inertia. (I did a 10 mile TT on it once, and did well under 30 mins) Brakes were completely ineffective, especially when wet, I nearly ended up in Lulwoth Cove during a short touring holiday. 😀
