Does anyone make a repro M-8 grenade launcher for the M-1 carbine that is not $220?

Good Day All,
Although I'm deployed at the moment, I did have a chance to look at GB and saw this Carbine M8 rifle grenade launcher for sale (M8 Grenade Launcher - M1 Carbine - Reproduction : WW1 WW2 Collectibles at GunBroker.com). I was told by the seller there were no markings except for the range markings. He posit that it *might* be a Korea war era piece. Has anyone seen a post GI WW2 production manufactured M8?
This was advertised as a reproduction and the price seemed quite fair at $85 so I'm not worried if its a repro. I'm just curious as to its origin.
Regards,
Michael
