I have in my stash an original never fitted 914-6-wv-porsche badge for sale -see pics below. £150 or going on ebay. This was the badge used for the few 914-6 sold in Europe. They were never imported into England (not even the 914-4 officially). US cars had the 914-6 moniker. Some of the GT cars like the Luftansa car shown in link below had this badge.
