For the record, I initially thought it was a Ross bayonet prior to purchasing and researching it. I looked at some images of Ross bayonets afterward and knew I was wrong and yes, the seller had corrected me after that, but the correction is what led me to purchase it in the first place. Once that was done, then I went on with researching markings.
Furthermore, this was the second bayonet I had ever purchased, with the first being a socket bayonet from a far earlier period. Forgive me for not having a library of reference material prior to venturing into the world of collecting the occasional military antique here and there. I've only collected a goulash of civilian antiques up until this point. Come to think of it, I haven't had reference material for anything that I've collected thus far, and it's all turned out peachy anyway.
That is not to say that life does not provide learning experiences, this is indeed helpful (albeit a tad unnecessarily scolding, but no matter). And while reference material is crucial and handy when you need it, sometimes that's the joy of this whole thing, learning and discovering as you go along, sometimes after you've already brought it home and are studying it (in moderation and depending on what you're picking up of course).
Food for thought anyhow, not sure when I'll be picking up the next bayonet. Could be a couple of weeks, could be a couple of years.
