Barrel marking mystery

[The_Evil_Scooter]

I got a K11 Carbine made in 1926, upon taking the stock off, I noticed a marking on the underside of the barrel, close to receiver: RHCe (or RIICe).  After searching the web, I can't figure out what RHCe means.  I believe this is where the barrel manufacturer leaves there mark, but doesnt match Sig or Hammerli markings. Anyone here know what this means and/or who the manufacturer is?  Thank you in advance.
