RAD buckle opinions please

[MattS]

This was the other buckle in the box I got (see the SS buckle). It has the tab and appears unmarked. What is this one worth? Thanks for your help guys!

Back side, no markings, just some old dirt.

Matt,

another original buckle with period added tab : try to carefully look at the smooth area delimited by four tabs, may be the maker marking is there (oLc in a diamond).
