Thanks for all the encouraging answers.
I have discussed the TTL issue with the vendor, who is willing to "recalibrate" the meter.
I have, also, put a second film through the camera using a hand-held meter this time: I have yet to see the results of either film, but have my fingers crossed.
In spite of the heft (the handle really helps with this) and the very loud shutter (and no MLU), I do like the beast very much, and have found it quite easy to use hand-held. (Of course, I have yet to see any results -which should become available on Friday- but I'm hoping).
