I bought 500ml of TEA from Rayco before they closed/were sold.
The guy who is supposed to have bought Rayco is David Jenkins who posted his phone number on photo.net for people to contact him back in May (I'll PM it to you rather than post it here, just in case he no longer wants it public). Given that there is still no web site, at least 6 months later, I don't know if he is still interested or has even started trading as Rayco.
Cheers, Bob.
P.S.. I'm surprised about Rose Chemicals - TEA seems to be quite widely used in the beauty-care industry which they claim to supply... Ho hum...
