I'm in.
Two years ago, when Joe needed help, Simon donated a sweet "Scarlet Kingsnake" Phantom to the Spring Castle gear auction. I bought it for the sum of $300 plus an additional small donation and credit card fee. Simon had got it from a previous charity event and simply "passed it forward." I have played with it occasionally since then and put a few eliminations on it. It has served me well and I have enjoyed my time with it.
Given similar circumstances, it is my humble honor to donate the gun once again.
I will donate the following gun to the auction at Spring Castle this year:

EDIT: It will also come with an 11" nickel CCI barrel and a set of detent rings in addition to what is shown.
If we need to set up a PayPal account for donations, I can offer mine if nothing else is available. I will offer to match any fees PayPal takes so that we don't lose any money. Still, I would encourage anyone that can make it to Castle to simply bring cash/check there for simplicity's sake.
Drum, I think you should cross-post this at SCP when you get a chance.
