mannlicher Schoenauer in 7x57 mauser

I have a rebarreled 1908 mannlicher Schoenauer. It must've been rebarreled a long time ago to 7x57. Everything works as it should which is awesome because custom work on these rifles is difficult due to the rotary magazine. Beautiful bluing and very good bore. Shoots heavy bullets very well. Claw mounted scope works very well and attach/detaches very well. Has tunnels in the rings so you can see the irons with the scope attached. 

I'm looking to trade this, im looking for:

Ross in .280 ross

318 Westley Richards rifle or barrel and / or reamer

505 gibbs or 500 Jeffery

Im also looking for a really nice .275 rigby (7x57) or mannlicher Schoenauer in 6.5x54

Will sell for $1800
