no, browning used to offer both engraving and gold fill- ie a grade 1 bar would be the straight blued model, a grade 2 would have some gold inlay, and the grade 3 would be a full custom job- some have minature animals , and can go as high as you want- most folks have only seen the blued models, but i used to have a catalogue with the codewords for the factory to make the model desired- we're talking belgium here, not north america or japan;
this engraving, gold inlay and fillagree has been offered on the bar, a5, and hi-power afaik- there's also a renaissance model of the hi-power i've seen at tiffany level engraving- try about 4k - and it has both gold inlay and filagree engraving
