LUGER BLUE PRINTS / any Source ?

[relichunter1]

Hi, Can any one tell me where to find LUGER Blue Prints for all model types ? Paper or CD is OK .. I have found moderator Here on this Fantastic site who offers such a CD but I have not been able to make contact yet .. I'm still looking for More sources .. I just payed a thousand dollars ,for Many books ,only to find ,NONE of them offer OVER ALL LENGHTS of lugers .. There is this ONE small field type guide for only 5.00 BUT they list a PO8 over all lenght as "8.75" inches .. I belive i'm reading this correctly to say 8 " and 3/4" total .. This guide stated Barrel lenght is 4.0" .. I measured My 1940 PO8 and got for overall lenght 8.7/16ths , clearly UNDER 8.1/2 inches let alone 8.3/4 the Booklet states .. Also upon a second measurement I Have a over all measurement on my PO8 from 1940 too be closer too 8.13/32nds .. Anyway PLEASE suggest any BOOK/ source that contains such accurate Data for over all lenght .. Thanks relichunter1
