I have only seen 5 or 6 rod bayonet rifles that I thought were real. On the rifles that were correct the trigger guard had a very distinct shape. I also found this TG on a later rifle that appeared to be a rebuild. My RB 1903 in numbered 57294 and has this trigger guard (as well as the front stacking swivel with the machined flat). I have photos I can send to someone but I have not yet mastered posting photos here. The photo shows the RB 1903 above with the later 1903 trigger guard below.
