This is an eBay ad from a 1956 magazine for a GBG DETATOPS Aluminum hardtop of MGA. This is the only one I have seen that is aluminum, other than the factory supplied Vanden Plas top. (Click for larger image).

"I have tried to help an old member of the MGA society in Denmark, Europe identifying what kind of hardtop he owns. ... As far as I can understand you have only seen one made in aluminum apart from the original made by Vanden Plas, namely being one made by GBG Detatops. I have attached pictures of the one in question and wonder if you think it is a GBG Detatop"?

"If you have not seen such top before, it must indeed be rare. We have tried to locate any stampings but have so far not been able to, so the manufacturer is still a mystery. It was saved from the scrap bin some years ago. I have attached some more pictures for your files".


Yes indeed, I think we have finally found one bonafide example of a genuine GBG Detatop aluminum hardtop for MGA. And it only took 11 years from first posting.
