	Marco has given some catalog prices. However, being a Pentax
	Discussion List member, as well as this list, I should alert
	you that this lens is a rather "collectable" one as well as being
	a specificly designed tool for certain things like scientific 
	research in those UV and IR wavelengths. the non-glass optics
	allow for extremely good correction of chromatic abberations across
	a very wide range of wavelengths.

	A specimen w/ all the goodies, as you describe, was on EBay w/in
	the last few months or so. I don't know the outcome - info on past
	auctions may be there, don't know that either.

	I do have the Pentax SP II pamphlet which has the description of the
	lens, as well as a 300mm designed with similar exotic materials.
	I can scan it & email if contacted  off-list.  
	 
	Bill
