Want to Buy WTB Kodak 2D 8x10 to 4x5 reducing back

I'd like to buy a 4x5 reducing back for an 8x10 Kodak 2D. I'll need it shipped to Seoul, South Korea - or if something comes up soon shipping to the UK this December would also be possible (I'll be in the UK visiting home this month). I'd prefer whichever was cheaper, though the gear will end up in Seoul.

I've got a spare 2D front rail which might be available for trade if anyone is interested. I didn't actually try the rail yet (it's in Seoul, my 2D is still in the UK). Let me know what you've got. Thanks for reading, and have a good day!

It's been suggested that I should clarify what sort of 2D rail I've got, I have the (earlier?) version with a key type fastening system, not a bolt.

I don't need reducing backs any more...I still have a spare rail if anyone is interested.
