I already just replied to you, but I'm not sure that it went through, as when i pushed the Reply button, it deleted itself! So, here it goes again...
I had said that I am a neophyte with Alfa Romeo parts, and don't have any idea what you might think this 2600 intake manifold is worth, but if I can trust your opinion that it is in good shape except for the welded up crack on the bottom edge (do you know how that crack got made?---and, could you tell before you had it repaired whether it was badly corroded inside in that area?---can you even see into the water jacket of the manifold in that area? Anyway, I would be willing to offer you $1000 for it on your word that it is good usable condition, but would like to talk personally with you regarding payment methods and shipping, etc. I could call you at the time and number that you give me, as I tried to send my phone number to you in an earlier reply, but the system kicked it back saying that I could not include phone numbers or email addresses, so I don't know how to work with this system, but hope you do!
So, let me know the next step...
