Um, if you have the time to sweat out an eBay auction this lens http://cgi.ebay.com/Schneider-100mm-...QQcmdZViewItem would be more useful on y'r Galvin than would, say, a 101/4.5 Ektar or Raptar or Optar (= Raptar). More coverage than the tessars.

I have no connection with the lens on offer, but if I had a 2x3 view camera -- I shoot 2x3 Graphics, can't use much coverage -- and needed a normal lens I'd bid on it.

Good luck, have fun,

Dan
