Lawrance Hurst's letter (AJ 13.4.00) expressed concern about the accuracy of my three articles (starting AJ 23.3.00) on dating buildings by their exemplary structural components and systems.
He has obviously overlooked my first article, which explicitly advised readers to beware of more extreme examples coming to light from time to time, either earlier or later than the specific dates which are given in my chronology charts.
Hurst's letter actually reinforces my caveat with his tales of rat-trap brickwork later than my specific date of 1854, which incidentally was the Coleshill Model Farm, near Swindon.
I also have anecdotal evidence of rat-trap bond being used circa 1900 in back-additions of South Wales houses but, for research and databases to move forward, they must be founded on first-hand evidence, not hearsay.
If Hurst or any of your readers has verifiable evidence which can expand any aspect of my chronology charts, I shall be delighted to hear from them at Cameron Taylor Bedford, Lorne Close, London NW8 7JJ.
