I said I had ulterior motives 
Yes, but you didn't say what they are!
Anyway it is a nice church, not a huge evangelical conglomerate.
Does that make a difference? And is not that church part of such a conglomerate?
yes I have been seduced inside the house of god
That's as good a place as any to be seduced...
by a piano but do not fear I am not getting religious
Ah, sorry - should have read abit more before answering; getting seduced into the house of God by a piano seems as good an excuse as any, so maybe I wasn't so far out in my previous remark.
I do not know what year it is
It's 2007 up over; not sure what it is down under...
tell me all about Blechsteins - how do they rate as pianos? Are they good? They must be if wolfi plays one.
Ah - more haste, less speed once again; you mean you don't know the year of the piano. Just check its number and you can find that out on the internet.
Is it worth investing in getting restored, in your view? Is this a good find?
Much depends on the amount of work that requires to be done and the cost of doing it; if the soundboard's still in near-perfect condition, it might be worth a go but, if it's not, it would probably not be.
Best,
