Yes there was DL version... looking at old ad's inn AGW etc.
Never seen one in person though... thanks for the feedback, looks like I've found one.
Hmm. Was it a factory-deluxe, or upgraded by a third-party or shop as a special edition (ie SFS)? Short of Beeman adverts, I've not seen any factory reference to a deluxe version, and it's seemingly not mentioned in Chris Thrale's book.
