Look Ma, No Hands!
It is a Raleigh-made Dunelt with a Trygg type center stand. Looks mid to late 1960s to me. Raleigh called this a Sprite model, with 5 speed derailler instead of the S5 Sturmey internal gear hub. Three places to check for a serial in this era: on the top side of the lug near the seat post, on the back side of the seat tube, and on the rear drops. The 1960s were a transitional time for serial numbers and serial locations at Raleigh. I dont see one on the bottom bracket in these pictures, but that is a possibility too. Raleigh was messing with a lot of its conventions in the 60s.
By top of the seat lug, I mean the upward facing surface- Raleigh started putting them there in about 1970.

Regarding vintage: Dunelt (and Triumph) being the cheaper "B" line bike (that's what my boss at the bike shop I worked at 50 years ago called them) normally got any components a year or so after the parent brand. Raleigh Sprites thru the '69 model year were still using S-A S-5 hubs and 26" wheels, went to Huret Allvit, 5-speed freewheel and 27" wheels starting in 1970. Well, that's at least what was coming thru A.R. Adams Cycle in Erie, PA back in the day. I'm certainly not disputing the catalog pictures, but I've never seen that chain guard on a derailleur equipped 5-speed Sprite. Once they replaced the S-A version, they were coming thru with a regular hockey stick style chainguard, and the 10-speed version were essentially Raleigh Record's with fenders, flat bars and mattress saddle.
One thing I'm finding amusing is that the "5 speed" decal on the downtube is identical to the one on my S-A powered '69 Sprite.
We carried Triumph and Dunelt at the shop, but they were all 3-speed downmarket versions of the Raleigh Sports. Occasionally, we'd get in a 10-speed version of those brands, bikes that the boss would really get pissed off receiving because they used a lot of Raleigh Record components, but were obviously cheaper than the Record so we sure couldn't sell them for the Record's $100.00 . . . . . . . . . . . and we were dying for any Raleigh 10-speeds we could get in. I do remember them having those long Huret levers mounted on the downtube, while the Raleigh derailleur bikes had the more normal length levers.
I often wonder just what Raleigh's distribution channels were like. In the Richmond, VA area, I've owned a number of Raleigh variants that are majorly different from the bikes of the same model names we were getting in northwestern PA.
