I just bought a huge... make that HUGE! lot of photo and darkroom equipment on eBay. Included in it is an old rolleicord that has "shutter problems". I know Grimes is the place to go for LF shutters (and spanner wrenches!). Where do/would you go for TLR service? The only place I have ever had MF gear serviced is Mamiya, but that was Mamiya gear. Thanks!
