I've got a Gundalach convertible which is in need of some repairs.

Would anyone be able to recommend someone who might be able to help me?

It's in the shutter... sometimes works, sometimes won't... you know how it is sometimes.... more than a bit annoying....

If it's in a Alphax/Betax shutter, and you're intrepid, unscrew the front and rear elements, give 'er a good lighter fluid bath, cycling the shutter on one of the higher speed, and exercising the aperture blades while drying, you might be surprised, the alphax/betax shutters are nearly indestructible.

Better still, trike (trichloroethane) or ether. I have seen it asserted that 5% clock oil in the trike/ether will lubricate the shutter bearings but I've found that plain, light organic solvents are fine.

Cheers,

I use a trichlor blend as well, have a widemouth pickle jar half full that I just drop a shutter into for an hour or so, though it's quite a bit harder for your average person to find trichlor or one of it's replacements.
