Very little is known about Hailwood & Ackroyd, or its preceding company Ackroyd & Best.
When I did this work a couple of years back hoping to find some art glass representations, all I came up with was lamp shades or panels, such as found in BGBtW 'The Charioteers'.
Most adverts suggest that the shades were either opaque (White or Ivory), or patterned. My observations suggest that the patterns were often black transfers and either hand painted or sprayed.
There are often hand painted codes, but as yet I haven't been able to record enough of them to break that code - although on some occasions they do appear to have a date. As yet none seem to be consistent!
My initial interest was through the art glass that appears from time to time with an acid etched mark. Apropos that, Manley says that it is only worth collecting pieces if they are marked. I say, you wouldn't know they were Hailware unless their marked.
Even though I have met a part of the Hailwood family and photographed their collection of glass unless they were marked I wasn't prepared to believe an item was by the company. Indeed there was a piece of Pyrex that was pulled out of the cupboard that was initially thought to be by Hailware! Difficult to point that sort of thing out I have to tell you.
Because of the lack of catalogues (I have one which yet again deals with lighting) the representations help with dating, but still only keep us in the world of lighting, whether commercial, or domestic. They also produced their own metal ware for the light fittings.
I have kept my research quiet since so little comes along through the internet and visiting various source materials is both time consuming and expensive (if you travel to Leeds and want to stay to go through the small amount of material in the archives, etc., then overnighting is a must.).
So far advertising locally has borne very little other than what should be regarded as hearsay, although the appeal through my website has over the years. The 'good' thing about hearsay of course is that you can follow that thread to see where it might lead
PS. Sadly I have been unable to do any research this year since my Mum passed away, and am unlikely to until her estate is sorted out, however any imformation would be gratefully received and filed for future use. [Credits always given/made]. Nigel
