You are right, there are two of these:
F-AZAV and
F-AZAX.
The machines for
Lawrence were made by Film Aviation Services at Croydon, one Fok D.VII and two Ru C. ?.Maybe the latter were further
modified around the engine and went to France.
In the seventies there was a BBC series and they had an Alb C.I, a description appeared in Scale Models but I don't have it anymore.
The conversion was done by ?Air Bianchi? or similar.
The replicas in question were featured in Aeroplane Monthly but again I don't have them anymore.
