As Mike Butler has already pointed out, Pearsons Cycles is avery long-established company currently trading from Sutton, in Surrey. I don't know whether this was the company's original address, but there have been there as long as I remember..about 30 years.
They have a web-site at: http://www.pearsonscycles.co.uk...but I'm not sure it will help you that much..although there will no doubt be an email address should transfers be required.
Like many companies they used to have a range of steel frames under the Pearson brand, and I seem to recall the shop supporting a cyclo-cross team back in the late 80s. Not sure who built the frames..but I think they were out-sourced, probably from someone like Nigel Dean up in Lincolnshire, who built a lot of OEM frames for good-sized shops.
