Carol at Flutot's almost always states that her forte is shutter repair...not lens work.
If possible, she even asks that you not send the glass with the shutter, (she mostly does LF shutters).
So, (in your case) with a TLR group, (which she also repairs), she would probably only be interested in
repairing the lens-set with the bad shutter, rather then swaping the good glass out of the bad shutter.
