You are not taking this seriously Jemmo .

None of you will make good detectives or investigators just think it through the clue is you will find the answer on e-bay,think where on e-bay are you likely to find the answer to this question.

ebay coach sales?

You wont find the answer in that section

Wilfreda Beehive?

Sorry its not them in the 1960's they were both were separate companies Wilfreda operating from Bawtry & Beehive operating from Adwick.
Your getting close there are at least three similar items for sale on e-bay at the moment that will give you the correct answer.

West Yorkshire?

Sorry not West Yorkshire this was a well known coach hire company located in Doncaster

Buckley's?
Welsh's?
Wilson's?

Sorry none of those I dont think they were around in the 1960's.

The company your looking for were based on York Rd

Edwards?

No there were Standard Triumph car dealers next door to Thompson's Vauxhall Bedford dealers

Heres a bit of help the name of the company appears as an advert on an item that's for sale on e-bay. the item that's for sale relates to the Dons.

Parker's?
Yes definitely Parker's Luxury Coaches!
