Kelston green line plate is Warwick d016

Found this cool luncheon plate today, has a single green line, and gold edge. I can't find a pattern name for it.

Only has the Kelston stamp.

I've seen "DB Ltd" that has the gold edge and green line but the additional "DB logo " and of course vitrified (I think.)
Thats the nearest I can see to that pattern

That was my thought too Janice, but alas no DB logo and not vitrified. Lovely plate though.

I love the older style stuff - anything older & up to the mid 60's and 3 digits - trying to cap/limit my collecting ( who am I kidding) !

would this be warwick D16

You could be right Janice, unless the gold is a factor. Some plates have a very fine and precise gold line on the edge, and others a rather splotchy sort of covering (as in the demitasse cups & saucers). This has the fine line, and the cup looks more like the speckled one, but if that doesn't matter, then it could well be.
