heidelbergensis 

Hey folks!

I know this is a bit of a long shot, but I'm looking to acquire some Herse cranks for my Eisentraut restoration project, and thought I'd throw this out there before I buy a new set directly from their website.

Not too worried about the chainrings or overall condition, just that they are the double chainring model. My preferred length would be 171mm, but I would also consider the 177mm arm length, too.

Thanks for your time!
