I have a Ansco Speedex 4.5 Special R 120film and I need to get it cleaned. I have already read that the grease/ lubrication used for the moving parts is know to harden or solidfiy. The rangefinder dial is completely stuck and the focus ring is having trouble moving. I would like to get this camera restored so I can use it at its full potential. I'm having trouble looking for a good repair shop and I am wondering if anyone knows of a place prefferably in the Los Angeles area. Thank you. Sincerely, Craig K.
