Wanted: razorback lascannon

[JAC]

Hi all, I'm after a right handed razorback lascannon if anyone has one.

[Darkson (Simon)]

Is that like a left-handed screwdriver?

Lol. The space marine equivalent!
I'll take a pair of anyone has them, but only want the one for the right hand side of the turret. I'm converting a pair of razorbacks to be lascannon and twin linked plasma guns for the escalation campaign but don't want the to be mis-matched if I can avoid it.
Willing to pay cash, biscuits or other parts from my bits box!
