After looking for photographs for some time and using map studies, I think I have at least the outline of 502 (16) New Oxford Street identified. It is indeed a substantial building that must have had 8,000 sq. feet of floor space.

That was the quintessential London "factory," perhaps the largest of its kind at the time. Donald Dallas used to walk past the building before it was rebuilt and I've asked him to confirm the preliminary results about its location. Surely someone has tourist photos of that block from the 1960's. (Edit: Donald Dallas has confirmed that this was indeed the area of Reilly's shop at 502 (16) New Oxford Street).

This has been posted on the history:
