Sell or Trade - Omniswivel Gas Switch Block

I have a brand new, never used but old stock Omniswivel gas switch block. Part number GSB-R
http://omniswivel.com/Products/GSB/GasSwitchBlock.html

It is the right hand (most common) configuration. The only difference is that this was from a limited run that Omniswivel did for Deep Outdoors, so it has the Deep Outdoors logo on it. You can confirm with Omniswivel that this is indeed their product. Never been wet.

I need the less common left hand configuration. Omniswivel said they sell more right hand by a ratio of 5 to 1.

Sells for $365. Looking to trade for left version, or make a decent offer.
