As mentioned please post a photo or two. Your friend will learn what he has and anyone else will be able to judge and also learn from the comments. There are many fake Lithgowicon hook quillon bayonets or should I say "reproductions". They are easy to spot (to the learned) because of their markings. An easy one is the inclusion of a Crown which of course is English/ Britishicon and was never associated with/ alongside the word Lithgow.
