I bought it at Newton. However, the lower ring is only available from a Morgan dealer. The number for the ring is REV. A. FLANGE 1143-6M M05 OD 126.0 X 27.OH CF350

Clemens, you were just quicker than me!

Your filler cap is mounted on top of the old one, which you made lockable. Mine is a complete replacement, also because I struggled with the original cap!
