Information about zis-151 crane Bleichert

Hello all,
I'm an italian modeller and I'm interested in russian trucks and lorry.
My favourite truck is ZiS-151, in past I've build an Italeri/Zvezda 1/35 scale katyusha, I really love this kit. Now I discovered on the web an old blak and white photograph of an Zis-151 crane Bleichert. Wow, is wonderful! Assoon as I've seen that photos I decided to build it in 1/35 scale.
Well, I started to build the basic zis truck but I need more information to self-build the crane.
Can anyone help me to find images or drawing about the crane Bleichert?
many thanks.
Geo

Thank you!
I know that kit exist but I don't buy it, I am trying to do it by myself because that kit cost over 80 euros (!!!!).
Anyway I use that image as reference.

Ciao
