A small railways crane for On30 scale.
All you need is to buy Spoked Wheels on axles from Pecco OO and Ho Scale for example.
Glue parts of the crane but think of the rotation and do not glue on wagon use small bolt and nut.
Make a crank, use some rob, attach the hook....
The crane must move free in circle. Block it when runing on tracks.
Is provided a French notice Hello French fellow FR
I have seen a message somewere
Also a service wagon for the crane staff to come in my collection....
many things in progress
