I had to do a little research. Got the C-330 instruction book
from Butkus.org I had not realized how much difference there is
between the 220 and 330. The 220 has only a manual shutter
cocking lever, which is on the shutter body. The 330 has a
cocking arrangement coupled to the film wind, like a Rolleiflex.
It also has a cocking lever on the shutter.
If I understand the problem the shutter seems to cock and
release when off the camera but the blades do not open and close.
I don't know what the problem is but if other lenses work on the
camera its not the camera. I suspect the shutter was damaged by
forcing it in some way. The shutter blades are operated by a ring
that is turned by the shutter motor. The blades are fastened to
the ring with pins on one side and to the fixed part of the
shutter housing on the other side. Either all the pins are broken
or the blade is not moving. I don't know the method of coupling
the blade ring to the motor in these shutters. I don't know who
works on these shutters but likely there are several competent
repair people. I don't know if there is any repair literature on
line, there may be. I am off to do an important errand but will
search when I get back. If there is a broken part you must go to
a pro, if something is just pushed out of place you may be able
to fix it yourself. If you are not experienced with shutters I
would go to a pro. These are good lenses and worth the cost of a
CLA. I have some knowledge of Compur, Compound and some American
made shutters but not the Japanese ones.

Shutter does not fire when off camera either. The link from camera body to
shutter lever will cock the shutter. But the blades do not open and close when
the lever is pressed. The lever returns to its resting position. It is not
jammed.

The shutter for the 220 is independent of the camera. The
shutter should cock and fire off the camera. Someone made a good
suggestion of trying the lens off the camera with both the trip
lever and the cable release. If it works off the camera the
shutter is OK. The camera has a link in it connected to the
double-exposure prevention. I don't know what is different in the
330. On the 220 there is a switch on the side for single or
double that disables the lock on the body release.
If the shutter is locked off the camera there is a problem
with it. Often these problems are simple to fix.
More information is needed about exactly what is happening
(or not happening).

That Mamiya 55mm TLR lens is great to use, specially with its
lens hood. I wonder if your shutter firing problem is in the
lens or in the camera - does the shutter fire OK off the camera?
Unfortunately the C330 seems to be prone to malfunction. That
may have something to do with the mechanical linkage between
winding on and cocking the shutter. The C220 is simpler and
seems more reliable.

Actually, I can cock the shutter, but it won't fire when I push the
shutter button. It's as though the shutter mechanism came unattached
from the shutter button link ( I am not a repairman, so I am guessing).

What do you mean by locked? Is the shutter jammed?
The 80mm is similar in design to the Schneider Xenotar.

But the lenses are wonderful.
