@Emanuele_Olivetti Emanuele thank you for your reply. that is indeed the lens.
I found an adapter on amazon.
I bought a “KECAY Leica M39 L39 Screw Mount (39mm thread) Lens to Sony NEX E-Mount Camera Adapter”
It cost me 13-50 GBP and I have used it successfully
Here are a couple of links to some pics I took with it
Thanks everyone for your input and help
