In the meantime, anyone still got an early, maybe 'A' prefix serial number early TG Co fill-from-the-top-bowl?[/QUOTE]

Peter, from what I've read, it seems that the 'B' preceeding the serial number represents the maker 'F. Barker & sons' even though it is stamped TG&CoLtd. If that is true then there may not be an 'A' prefix ... and even if there is, it may not necessarily preceed the 'B'.

confused ?
