Thanks for all the posts, really helpful and continues to be an interesting discussion on the merits of all the options, all of which are pretty damn great really.
Yes, 'piece of junk' is overstating things, but (subjectively, imho, with the copies I had etc...) the 35 v4s I had always felt a little too fragile for my own personal liking - but of course ymmv and variation in condition is extremely high in all of these lenses that can be 30+ years old.
A quick look at ebay shows me the 'steel rim' now commands a price between $7000 and $20,000 US Dollars!! (potentially the same cost as 25 x 40-Summicron-Cs!!)
That closes the door very firmly on that option unfortunately!
I'll have another review of this thread - thanks for the images Erik - and reconsider what it is I really want.
