Any black stick with a BSD serial is a proper stock stick sent to bitshopper.de for resale. The green stick, serial 22394, is not a seconds stick but I don't know how you ended up with it in UK unless you bought it second-hand. Either that or I have a reseller breaking the rules.
Let me ask again, who did you buy them from?
ahh ok i see. well the sellers name on ebay is: sottime
the three that i have on order are also from the same seller and they are also green.
while i have you please can you explain a little about the voltage adjuster? what is the home position of it and is it clockwise for more volts?
thank you
