Hello all, fairly new to LF photography and brand spanking new to using flashbulbs. I recently aquired a heiland Syncro-Special that seems to be missing the button(?). Is there any hope to restore this to working order? The rest is in almost perfect condition, and it would be a shame not to be able to use it.

Hmm --- not much response to this one, so I'll jump in. Try Midwest Photo Exchange, Pacific Rim Camera and Fred Lustig. You can find Fred's phone number on this site, through a search. No web site. Daytime calls only, please.
