MDT Polymer 10 round magazine for 3.08 / 6.5CM

I have an unused new in package spare MDT Polymer 10 round magazine suitable for .308 and 6.5 CM etc  new in packaging.  It was for a Tikka .308 but rifle that has since sold.  Part # 104447-FDE so could work with other calibers but you'd need to check.  I'd prefer trade for powder like IMR 4831 or 4350 or Barnes TTSX bullets /part cash if need be.
