Not from CS if that is Collectors Source, but one that I happened to see recently. The CS one that is online right now looks pretty grungey. Rusty and it has that dark, grease-soaked look that so many Ishies seem to have. That is for $325 and the one I am looking at is about the same I think, asking. But in far, far nicer condition.
I am torn because on the one hand re-chambering to commercial .410 is a sacrilege from a milsurp collection standpoint, yet adds immeasurably to the potential enjoyment of the piece.
Funny that if anyone talks about reaming out an Ishy 410 nobody bats an eye, but if you talked about changing the calibre of a No. 4 you'd be chased off the typical milsurp site and branded Bubba. Not trolling here, just observing. No doubt Ishy's occupy a certain untouchables' caste in many collectors eyes, but I find them as intriguing as anything else, in some cases more so.
