Thanks for your comments.
I bought all genuine parts from MB direct and complete rear modules - they are definitely my favourite of all the lenses. They set me back 110GBP each, which was only slightly more expensive than Performance Products! and I get an original invoice and all MB boxes to keep too.
BTW - I wish that was my plate

Weather's been good here with occasional showers 'April showers' we call it but in general it's getting warmer with some days up to 20degC. I live in the South East so it's always warm here ;-)
If weather permits I'll take a couple more piccies (hopefully with lid off) and post the odd one or two.
