The blades still in their original "The irons all need cleaning as there is some rust. A worthwhile project." state
The round 6, shortened, the only damaged part of the set. Seen after a first cleanup on my cheap oil-stone (I think it is made of concrete), that I keep dry. The tip shows some dip, so I could have used the ruler trick, but I finished it by lightly polishing it on a hard felt wheel with some Veritas green rouge.
This morning I spotted on ebay four planes of unspecified size, I thought it was a pair of 8 and a round 12 and 14, three of the four I am missing to have matched pairs. Made a half hearted attempt with a 21 £ bid and lost from a late(r) sniper. Anyway for now it's more important to use them.
