Again, no one on here will discuss these questions:

How much was a PW-5 brand new?

Is it not a rhetorical question? I believe my club's two PW5s in 1994 or 1995 (which were somewhere in the first five or six serial numbers) cost NZ$25000, or about US$15000.

What would that be worth in today's dollars with inflation?

That's US$24000 now, based on US inflation.

I suspect other factors such as the cost of living in Poland might be more relevant -- that looks to me more like a factor of 3.5 since the mid 90s, which would make a PW5 cost $52500 now.
