It's not a Raleigh product from what I can see. It also does not exactly match Phillips or Hercules (common non-Raleigh brands in the US). The fittings are 1950s-early 60s era. The coaster brake is common for bikes the English exported to the US. The Perry coaster was particularly common that period. If it's a Perry, you may be able to find a month and date stamp on the inside surface of the brake reaction arm. It certainly does have a "house brand" look to it. The serial number strike and location is kind of unique - the common places are the rear drop, bottom bracket, or seat lug. Head lug is sort of different place for it. The lug style is also different - it's a fishmouth design, but with the fishmouth having a band at its opening.
Two-tone paint like this was popular on English bikes in the 1950s-early 60s as well. The very long chrome shark blade on the front fender is also sort of unique. If I had to guess, and it's just a guess really, I'd say it's a house brand bike made for export to the US at a budget price point. They used generic (but still well-made) Brampton fittings, so those don't seem to have been made in-house. The brake levers are also generic (but again, they're well-made). Brampton was producing a lot of stuff in the mid-1950s for bikes exported to the US, so again that same time period. I can't name a maker offhand, and the Veteran Cycle Club library seems to have gone to a subscription-only model.
