I sold some Merlin frames at Bixby Knolls Bicycle Center in Long Beach, CA in 1972, so they were made at least until then. I thought they were still being sold in the UK, as I remember seeing the name listed in an advert in Cycling Weekly not too long ago.

-------------Original message------------------------- Lou; Merlin was bought out by JRJ in 1955. I'm not sure when the Merlin line ceased, as I believe that JRJ produced both Merlin anf JRJ frames simultaniously, possibly into the early 60s. As for Merlin Titanium, you're correct, as they started up in 1986.
