I thought the dropped center was the dunlop pattern, and that Raleigh started making them themselves after Dunlop and they parted ways. The standard rim, was used on the lower end bicycles. Damaged wheels were often replaced with cheap no-brand wheels from K-Mart, etc. Possibly a dealer put the wrong wheel on, maybe one of the 16 yo mechanics not knowing the difference. My Dunelt had the cheaper rims standard, but I was able to tell the front was not original because it had 36 spokes, factory was 32/40 just like the Raleighs. Also parents can be sneaky, and not tell spouses and kids about little accidents, that they had repaired before coming home. Who knows what might have happened in the mists of time?
