Used, damaged, unusable Crosman Main CO2 tube wanted ...

[Washbush]

Hi all ...

I am in the process of putting together my own personal dream CO2 target pistol from all Crosman available parts.  I am using the Marauder 2 stage trigger group, a nice LW barrel, my own gas valve modifications, my own grips, adjustable length striker, adjustable hammer blow weight, etc.  Now I am in the process of putting a 1701 Silhouette breech on the CO2 main tube.  This mounts with 4 screws and they are drilled vertically on the sloping sides of the tube.  I think I need make a jig and to practise drilling and tapping something that is off camber like that.  So, I am looking for an old tube to practise on. It can be dented or bent or rusty or otherwise useless for intended use as all I want it for is a scrap piece to drill and tap until my confidence level goes up a bit. If you have something like that, let me know what you want for it and I will PayPal you right away.
