Probably a Coleman Milne conversion - initially built for the funeral trade on an extended floor pan - the roof & rear wing skins were manufactured from fibreglass - I think that Coleman were the original coachbuilders of hearses / limousine's - Woodhall Nicholson (now own Coleman Milne and various other specialist vehicle conversion companies) Another conversion company Eagle Specialist Vehicles build similar vehicles - Once upon a time there were all based within a mile of each other - Wigan Road on the outskirts of Bolton
Not a car but relevant to the above post - Here in the colonies, the CIBC Bank (Canadian Inperial Bank of Commerce thank you very much) Just changed their Logo. I must admit I was a tad surprised.
