Mystery Shocks

Hi all,

Attached are pictures of the shocks that were fitted to my Titan Mk6 as she came from her previous owner. They have now been replaced with steel-bodied Konis, but I am now looking into having these rebuilt, either to use as spares or to pass on. Unfortunately there are very few markings on the shocks to help identify them - certainly no logos or company names. Does anybody recognise these particular shocks?

Thanks in advance,

Sam
