AHA! The rear brake caliper has a 63 under the 610 on one of the arms. Rear brake calipers are well known to be the most reliable dating method for 1963 Raleigh/Carlton hybrids.
Edit - the front caliper is not a Weinmann, it has a logo I don't recognize that appears to be a
JS within a circle.
Stem is stuck pretty hard. Too bad - the Hiduminium stem with the cable stop hole might be the most valuable piece on the bike. Well, aside from the seatclamp nut with the red "C" face on it.
