AGFA BILLY COMPUR

I have an AGFA BILLY COMPUR 105mm 4.5 SOLINAR second version produced from 1948 to 1949. Can someone please tell me how many were produced?

According to H.Thiele at least 13,000 Billy Rekord II were equipped with the105mm/4.5 Solinar lens 1950-1956 and some 3,000 with 10.5cm pre-war versions. There were also 13,200 B.R. III with this lens.
