OP Parker Books- fair price??

[Old and Reliable]

A PGCA member recently contacted me regarding a later (SN 223xxx) 12 Gauge Trojan receiver I have with the hammers, top lever, etc- with the possible view towards buying some or all of the components for his Parker parts projects--

I have the Numrich schematic, went there and listed all the parts and the Numrich code and prices, whether they were sold out or in stock--

But I also noticed they listed the now late Ed Muderlak's book "Parker Guns- The Old Reliable" at $66.70, and that made me wonder. If this gentleman wants the Trojan parts, I want to price them fairly, allowing for the law of supply and demand- I have a MINT copy of that same book in DJ- second ed. and inside the fly-leaf it is priced $49.95-- Would it seem that Numrich has a first or signed ed. to command that higher price?

Are they parts they offer for sale for Parkers, L.C. Smiths, etc- all older original parts? I had read that some of the parts from the Japanese mfg. Reproduction Parkers would fit older Meriden mfg. Parkers? Is this true?
