The Murphy A862G uses a UCL82 and a UY85 like your A852G. The picture of the chassis in the Trader sheet for the A862G looks very much like your picture. The Trader sheet for the A862G is available here

and in my opinion is certainly worth a punt.
EDIT: I have just noticed that the Trader sheet calls the A862G the "Majorette" which fits in with Edward's suggestion above.
