EARLY BRITISH BAYONET W/HANGER

I have to start this off by saying maybe it is not English? not my field of collection but just thought it was in good condition and I normally do not see early bayonets with the belt hanger so I bought it. Now you guys can tell me what I bought and if I paid too much for it. So here goes the description the Blade is Three sided and 17" long marked with a crown with a 10 under it and something stamped above the crown I did not see a broad arrow proof mark but I do not know when that went into effect with GB.The blade is bright with some surface rust and black marks. The scabbard leather is complete with the stitching intact the drag and throat are complete. The leather hanger has the letter B stamped on the reverse and the number 3 a smaller 3 is stamped on the lower portion of the hanger. Condition very good
