I've never seen a lightweight (or roadster) Raleigh Glider that preceded the 60's just as I've never seen a Clubman made later than the early 50's. That's not to say they weren't made but Eatons sourced Gliders from other companies in the pre war and post war eras. I've owned 2 of them and they were both British standard Birmingham style bikes.
It's certainly not unethical to dress it up as whatever model you want as a keeper. Selling it would be another thing. Think Windsor and Cinelli.
Now that I've got all defensive about it, I'd love to see some pics. It's not that I don't want it to exist, I just want it for myself.
