Matt from memory there are 4 different types of tickford caps.

There is one with is completly plastic, to suit the s1 16inch 'sawblade' rims

There is the fully metal version as seen above in pic 3/4

There is then the version you remember. A plastic cap with a metal cover over the top. Like the ones in first and second pic, but with a tickford badge.

Then there is the fourth type, which is kinda like the reverse of pics 3/4. It is put into the rim from behind and has the flange/flare at the back. These were on t-series rims only. Can't remember which ones though.

Cheers
