To be honest I have no idea of what they are worth the Nelson cost me £160 and the Razor cost me £ 150 The nelson just needs a little tlc the other is fine and has Slam Fire to
I didn't want to rip anyone off so offers around £30-£40 there is a butt changer with the Nelson but that also needs tlc
Where do you live ?I have also just found an old bit of webbing that holds the sparklet c02 and as I said there is a c02 but changer in the loft to dig out and maybe a silencer so how about £50 for the lot or I would trade for an 02 Bottle of decent size
I also have just dug out the Butt changer and silencer you just need a Quick connector you know the plumbing one for connecting to pipes the same size together
