I sent an email to this guy to try to ascertain the source, quality, finish etc and he has given me permission to publish his reply - I was happy with what he told me and pleased that he is using a paint finish (I hate powder coating to pieces) - I have already ordered through ebay and will report back my experience - I think this sounds like a better option than paying £50 to £100 for a 10 year old part or buying another crappy new one from Land Rover.
Here is his reply.
Hi John
We had exactly the same problem with sourcing 1 for our own truck like yourself not wanting to pay dealer prices or wanting a second hand 1. I myself was also in the engineering trade, time served welder, fabricator and my friend has a fabrication firm so we got together and started making a few until we got the materials and specification spot on. Now we have, we have started to sell them on.
To be completely honest the genuine parts are not a patch on ours quality wise, ours are a little heavier but I guarantee will last at least twice as long. We primer them first obviously and then we finished them off with a zinc based paint as we wanted more protection than from a normal gloss or matt finish paint.
We have sold quite a few of these now and have only had positive feedback about them, now we are in the swing of things with them and have jigs to make in and can supply high demand the next step was to try the forums, I'm on a few on Facebook buts that's it so any help would be much appreciated.
Hope this answers all your questions and look forward to hear from you soon.
Many thanks
Andrew Starling
