Sadly, it's likely a reproduction & i've been asked not to post them by the management.
The 'real' one has a 24.75 in. blade, perfect for naval use. Can't see any markings but there is an area near the guard that is scratched an looks like it may have had a two line label along the blade rather than across. it instantly became one of my favourites. posted here earlier:
