I hope the experts here can help me with a 1907 bayonet I just got. From my research, all should be stamped 1907 as a model designation. A manufactuer's year should follow. Mine does not appear to have room for an additional line of text. It looks like it has an ER under the crown instead of a GR but it is hard to tell. I am assuming mine may have actually been made in 1907 with a hooked quillion. It has what looks like a 1925 arsenal mark so I am assuming the quillion was modified then (if not before). It looks like it was refurbished at least once and maybe twice. I'm looking for somebody to either confirm my analysis or correct me where I'm wrong. Any other info wold be appreciated. This one may go well with my 1904 Sparkbrook Mk1***. Thanks in advance!!
