Here are two nice SCA Otis Type LRIs-with NO embossing. Not sure why this mold style was produced with no reference to "Otis", or "Patent Aug 26, 1851", the usual embossing on Otis LRIs. Note too the odd brackets which seem to only have been used on these unembossed units. Looks like the one about to sell on the Eplace! Picked these up seperately, over the past 25+ years.
