I came across this wireline roll, pure luck :)
my father owned a fire safety company before he past away fore many years ago, I was yust looking in the storage room, and there it was ;)
what it cost and where too get it i simply don`t no, sorry. Â :|
hopefully not too exspensive.
but are you interested, we could perhaps make a trade,
30 cm (12 inch)barbed wire, u need 3 to 4 meters (13 foot) straight wire. send me a PM and maybe we can get a deal  :-)
its fun to DIY
make barbed wire around a prison camp, in the city etc… nice
