Thank Stick and Naj for your input,
Until tonight my theory was as follows:-
the main reflectors are still available from MBUK for about £160, my main problem is the fog lamp reflector which is NLA but I believe available elsewhere for about the same amount. the seals are still available at less than £100 per lamp, add this to the cost of bulbs and I am possibly up to around £500 per lamp not to mention the indicator reflector etc. LHD lamps are still available at around £1,200. My theory was that if i buy a new complete LHD lamp and sell off the new LHD lens and my old lamp assembly minus the RHD lens of course, if Ebay excels I may be lucky and upgrade to new lamps for the cost of reconditioning.
But,,,, I now have completely stripped both lights to the bare shells, one assembly looks recent and all I have done is clean up and respray the aluminium body and ordered a new glass/body seal, clean up reflectors, lubricate adjusters and replace all bulbs upgrading the dip/main to halogen (the 35w fog bulb is still available from MB and not expensive!)
The other assembly is a little more tired, the main reflector is acceptable for a driver, turn indicator also similar, but the fog reflector is very corroded. I am having this acid dipped to see if it will survive, if so, I plan to tidy it up and prime and then either chrome spray it or possibly try to wrap it in reflective foil similar to the car wraps we see nowadays, it may work, it may not. The main body of the lamp is slightly bowed somehow not allowing the lens to seal at all, hence the rusty fog light reflector I think!, so I will straighten, clean, spray and replace seal/bulbs as before. - Stick have you a fog lamp reflector just in case!
I will report back with progress.
One thing I would like to add is this, it's most likely in the wrong place but oh well!. With the help and information on this forum and the current UK weather I have in the last couple of weeks fully serviced my car including changing the scary gearbox oil filter, had the seats out and tidied up the carpets and trim, re conditioned my indicator switch - more scary, and am half way through my headlamp overhaul. Next is the timing chain due to mileage and then I hope to make it across the water to the Euro 2012 event!, thanks all
