Technical ID this mirror please

I was digging through some parts this evening, and rdn across this side view mirror. For the life of me, I can't figure out what year or make. Can anyone help? Thanks

 

For stàrters its broken ...

 

Accessory mirror made by one of the hundreds of aftermarket parts manufacturers.

 

Looks like an IH pickup/Scout mirror with a different head on it. Also a good sized piece of the base is missing. Someone likely will want that stalk though, they're pretty valuable mirrors. Here's an example on eBay.

or you could buy a pair of rusty ones for cheap

or a pair of new in the box for not too unreasonable price.

These don't say IH on them, I presume

 

I don't see where it's broken.

I thought it might be an ih mirror, but it seems slightly different.
