I'm always open to new pics & more/new/corrected info!. My "focus" on my site is on US military used items, I was hoping to stay away from all the commercial, export & foreign stuff as the topic just becomes too large but the problem is that some of it should be mentioned & identified, case in point, the W German/Eickhorn bayonets that are Colt marked, as far as I've been able to ascertain none of these were purchased or used by the US military so would be outside the "scope" for US used M7's, BUT they seem to be a very popular "collecting" theme in themselves so I put up some pics of them, those pics by the way were very kindly provided by the collector who was selling the M7 collection on Ebay a while ago. As said in one of the answers to this thread there is a huge number of "M7" bayonets out there, Philippine, Israeli, German, reportedly Thai etc, also a very large number of commercial products, some of the companies that had US military contracts sold off component parts surpluses on the commercial market which were then used in "new" production bayonets that were never US military issue/used. Add to this military M7's that were rebuilt/repaired/refinished & things get more confusing. There are also some experimental &/or very limited production M7 bayonets reported, the so-called "sniper M7" an experimental model reportedly built at Rock Island, the Navy M7 w/bowie style blade & MkI scabbard etc, I have pics of some of these that I haven't put up yet as there just isn't enough info on them (at least I don't have it!) to include them yet. At this point in my research on the topic of US military issue M7 bayonets the only ones I've confirmed are the Colt "601" style, MilPar, Conetta, FZR, & BOC bayonets as US military use during the VN war, Imperial possibly at the very end, BUT Imperials contract shows first deliveries in 1973 pretty much after US combat involvement (on a lg scale) was pretty much over, most Imperials were delivered after the VN war (at least US combat involvement), General Cutlery & Ontario are definitely post VN. The Imperial & Milpar M7's w/Colt marked blades are a big question, the Imperial/Colt M7's as to whether they were actually ever bought/purchased by the US military & the Milpar/Colt's same question & if they were actually made as such! Any M7 w/Colt markings would indicate the bayonets were made for Colt & sold thru them or licensed by them, needless to say this would increase the cost per M7 to the final buyer (US military), in 1963 the first contract was signed for the M7, believed to be Milpar, these bayonets were bought directly from Milpar by the US Govt, the M7 was basically a developement from the US M4 carbine bayonet, from what I've been able to find the bayonet for the AR15 as originally used w/the 601 was not a proprietary or design owned by Colt so the military simply used the modified M4 (as modified by Colt!) as their M7, now, tare the so-called MilPar/Colt M7's, if they were built as such, the earliest production by Milpar for the US military (1963-1964) & marked w/the Colt trademark on the blade a "concession" to Colt's rights/interest in the bayonets design before it was determined (or allowed by Colt) that the bayonet design wasn't "owned" by them (Colt), or were they simply M7's that were rebuilt using earlier Colt blades & Milpar crossguards, or were they an actual contract for Colt by Milpar? The Imperial/Colt M7's form what I can see (& I will point out, my "thought" & I've been wrong before LOL!), appear to be an actual contract for Colt by Imperial, interesting thing about these is they're NOT marked Imperial, just Colt on the blade, the fact that they're Imperial mfg comes from Imperial's records of the contract, these M7's all have the later curved runout on the blade which makes me believe they were post VN, & probably an export item. All the "definite" M7 bayonets made during the VN war & delivered to the US military show the 90 degree type runout, as does the M4 ithey were "based" on & the Colt "601" bayonets which preceeded them. The first "definite" US military contract M7 that I've seen that has the 90 degree runout is the General Cutlery made between 1985 & 1990 ("American Military bayonets of the 20th Century).
