Fixed loop lid, is it a Schlueter ??

Hi Guys.

I've had this pot awhile now,and as it does not appear to have a heatstamp,I cannot ID this pot,one way or the other, the loop shape leads to think it may well be a Schlueter, but as I say cannot find the "S" in the shell........ Any theories on this one,any help with this would be great,I have previously recieved feedback on this one being an "S" or a McCord.....Ah the mysteries of an M1


Any help with this one Fellas,would be greatly appreciated
