Guys, I won the bid on an eight inch 357 SuperMag barrel tube on eBay, It has arrived and is in great shape but is not a 357. I make it out to be either a 375 tube for a 375 SuperMag or a 41 tube for a 414 SuperMag or a 41 Magnum.
I plan to return it to seller on Monday but if anybody here wants it, get an email to me by Monday morning and we'll figure something out. I figure 375 and 41 caliber tubes don't grow on trees.
(I measure the groove diameter as too big for a 375 and too small for a 41. Either my measuring technique leaves something to be desired or I'm just plain nuts. I'll try to get a better measurement over the week end.)
