nice camera !
pva-glue and india ink ( thanks jeremy ! )
it works like a champ.
extend the bellows, and use the flashlight, and apply.
leave bellows extended until glue is dry. then see how it looks with flashlight.
re-apply as needed.
equinoxphoto.com also sells a bellows fix if you want a
concoction that is made by someone else.
have fun !
ps. sorry about your back !
the link should have read equinoxphotographic.com
( look under large format )
