Better pass on this one!
It may be (clearly isn't) o.k. now, but it will go soon.
The problem with metal foil shutter curtains is fatigue (has been since Hasselblad first put a stainless steel foil focal plane shutter in the 1600 F in 1948).
These thingies accelerate to a very high speed and then stop in a very short time.
The stresses make the thin foil buckle. To prevent that happening, the foil is corrugated, making it stiff in one direction, but still flexible in the other.
That works great, but as a result, the stresses are concentrated in the bends of the corrugation.
That eventually leads to small pin prick holes along the edges/bends with normal wear.
But will lead to total destruction when the foil is buckled in any other direction too.
Hasselblad tried several things to avoid those problems with metal foil shutter (they rejected the rubberized cloth shutters very early on: Victor's Leica would suffer when left out in the sun, with the sun burning holes in the cloth. So no cloth shutters for Victor...). But all they eventually did was change the steel for titanium.
That helps a lot to prevent the fatigue pin pricks. But does very little to rescue buckled shutters. They will still go completely, sooner or later.
So despite the fact that some buckled shutters are still in use, these thingies can not (!) take some beating and survive.
(Hence the shutter retraction mechanism introduced very shortly after the re-introduction of the metal foil shutter.)
So better stay away from this one.
That said, there is a man in the UK, John Emmett (of Broadcast Products Research Ltd), who offers to change the metal foil shutter against a plastic foil shutter.
It would appear to work.
