Would the revolver with the 1877 colt type grip frame ,simular to to the ones above have been made in Spain or Belgium,It had no markings other than a Sydney Australia retailers adress,it had British proof marks but lots of Belgium guns have these,IT was very well made ,as good as a colt or British revolver of the period,I was told it was Belgium but may be its Spanish,I have only seen a photo of one other the same so mabe I am looking in the wrong place
