Location has a huge bearing on what such treasures are worth.
Kevin,
I could put the most of that pile to very good use!!
Here in the land of few Listers I have TWICE bid up similar "piles" that could be built into a twin cylinder CS but was outbid. I am ashamed to admit how high I bid on one of them but somebody else wanted them worse than I. Some day I will own a CS twin,, someday
