I had a stem re-anodised by them and it was turned around very quickly, about 2 to 3 weeks all in. Not had anything sent to be de-chromed through them however I would say from my experience of chromers that they work in a parallel universe where their week runs at about 4 weeks of everyone elses time. So if he's sent them to someone and they said a week or two what they actually meant is a month or two
.
If it helps, I found Custom Parts to be very responsive, try emailing him at paul@lawson0212.fsnet.co.uk to see if you have any joy.
