I agree with prisoner and Moonclips. These look like Ahrends. The have a distinctive ridge on the fingergrooves where the Secret Service grips from Eagle are smooth. Also, the speedloader cutout is fairly distinctive on the Ahrends (although I have seen one picture of an Eagle set that was very similar...but not the finger grooves).
The wood may be cocobolo, or but I think it is moradillo (an option I think only Ahrends offers) due to the chocolate color and the lack of lighter colored striations.
As far as not being finished and sealed, I read an archived post when I was grip shopping that said Ahrends would send them unfinished on request...but I have no first hand knowledge.
