Looks like an Orbea, or possibly a Tracoala(sp.) revolver.
Can't quite make out the grip or frame crest, but probably an Orbea. From what I've gathered, the Orbeas are decently made revolvers.
Chambered for .38 long Colt. Will supposidly chamber and fire .38 Specials, but made for the lower powered .38 longs, a black powder round. So maybe not a good idea to try shoot .38 Specials in it!
