House Cleanout - Bayonet. What do I have here?

So my MIL passed away a little over a year ago and we've finally gotten around to cleaning out her house so we can put it onto the market. I was moving stuff out of her basement when I ran across this bayonet with scabbard hanging on a very old and moldy web belt. I can't tell the age of it so it might be WWII or Korea. Looking the bayonet over it's in really good shape with some surface rust. The scabbard is US marked. I don't see any markings on the bayonet itself. I'm thinking it goes with a Garand or maybe a 1903. So to the experts, what do I have?

Going to have to clean it up some and get rid of the surface rust.

 

it is a model of 1903 I got one too should be a stamp maybe utica ny or sa somewhere

 

OP said there's rust on the blade, so it can't be plastic. Looks like a M1905 bayonet.

If you can measure the blade length and post it here OP, that would help. If it's an M1905, the blade length should be right about 16".

 

Just wipe off the metal parts with an oily rag. Don't try to clean it further. Original finish is preferred on historical pieces.

 

No rust on the blade, just the furniture. Also, the 2 big rivets through the guard are a giveaway that it is the Navy training model.
You can also see the mold lines on the cast guard crosspiece not present on the real combat bayonets.
I agree this is a Navy MK1. Quite valuable.

 

And be careful, bakalite can be very brittle.

 

Unless cleaning reveals a "USN Mk I" stamp on the scabbard then the scabbard, alone, retails from US$85-95
The scabbards were often mismatched even in service, as, to increase production rates, the Navy Department dropped the scabbard throat marking requirement.

The M-1936 pistol belt, unless some good ink stamps appear, perhaps US$5-10

The USN Bayonet, Mk I, Training, with intact muzzle ring, and unbroken tip, ven with mild rusting on the metal, will be US$180-220.
Lifting the surface rust out with a bit of oil, and retaining the patina could add easily another US$50-100.

Now, some of these were issued to camp & shipyard guards and similar personnel, so that "the real thing" could go to war. So, every so often, really pristine versions will emerge.

The Training bayonet was only made from 1940 to 1942, but, a million or so were made.

Put the thing, as is, on eBay and you might clear some astronomical amounts with bidders chasing bidders.

The good "match" for this would be a Paris-Dunn Rifle, training--which is a wooden replica of the 1903 made in Canada as part of the 1940 War Preparedness Act. Those are available on eBay for US$250-400. A Rifle, Cal..30 Model of 1903, Drill, would also be a good match--but those are as scarce as honest politicians, and of similar expense.

They are a cool bit of history
