During the 1930's there were two similar Bonora type caps produced with the main difference being in the profile of the quick release lever itself, some having more of a tapered swirl shape which we note are being offered elsewhere. Ours are the original CMI (Central Motor Institute Ltd) design as produced for the MG factory in the 1930's and as shown above.

The initial sample run were completed with a non-original boss attached to the underside of the anchor arm. We suggested a modification to incorporate a concealed adjuster screw on the underside instead. There was also a problem in achieving a good chrome finish on the brass alloy casting. This issue has now been addressed by using an alternative chroming technique.

These filler caps are investment castings where the quality finish will be noticably different from sand castings.
