I have 2 of these Sarco bayonets. One with plastic handles and one leather handled. The leather handled looks exactly like the op. They came without scabbards 

Hey Charles, Sounds like you started digging in the right places. I'm gonna double down on the mishap reports. I have hundreds of military aircraft accident reports from mishaps in my neck of the woods. My hobby is looking for military aircraft crash sites. If you find news paper reports they have minimal information, you can go to Craig Fuller's AAIR site and find more information. Craig sells mishap reports. In them you will find little nuggets on base operations. I have a B-24 mishap report out of Rice AAF. This was the 5th bomber in a week to go down in sight of the base. Aircrews refused to fly until the problems were identified and addressed. You will not read things like this anyplace except in a report.               Yours  David

That is extremely cool, appreciate you sharing! I would love to have one like that in my collection even though its not military issue (though I'm sure many individuals in military service would be ecstatic to have this available to them as well). Your handle is closer in color/composition to the piece which started this discussion than most other Sarco bayos I've seen. Makes me wonder if someone took the Conetta MK2 blade and rolled their own with it. Would make sense why it doesn't look like any of the other Sarco Leather Handled MK2

Not everything cheap is a repro or bad! Just keep collecting and learning more. Try to get some 'hands on' with good patches at the shows. You can find a bargain gem put and about. Sometime the sellers have not done their due diligence and have no idea what they have. I have picked up some really nice patches due to the rarity or hard to identify aspect of them. LEARN your hobby, you will benefit in the military history you will learn and maybe make your wallet fatter too!  

Hi Mike, thanks for sharing Frank Trzaska's "Reproduction Recognition" page. I take it you think this is one of the Sarco commercial pieces then? I would love your opinion on how they made the leather handles look so clean/dark on this particular piece compared to the leather handles on most Sarco Conetta MK2 bayonets. Even the ones in the advertisement you show have much lighter colored handles and the leather doesn't seem as tight/uniform.

Do like all the kids do. Videotape you opening it, then post on YouTube. Then sell the GL with the video included.

Thanks for the comment Dennis, good to know that some of them might not fit the AR. I wonder if it was a problem with the bayonet or the lug on the rifle. As I understand it, many manufacturers of AR-15s made them with non functional lugs or non milspec lugs during the time period these were made by Sarco. I would love to get one (or multiples) for $29 but these days even getting one for a $100 seems like a good deal when most are going for at least $200-$300.
