Thanks indeed- I plan to buy my reference copies of TPS as soon as I have sold the dup.o.p. books I have listed (Thanks John Dunkle for the forebearance- they aren't really 'gun parts") on our for sale site. I just received the LC Smith books by Brophy- the Brownell's 1981 book on Specifications is worth a small fortune, IMO- so we shall see!!
