Luke Grappling Hook Identification

I need some help in identifying what this is exactly. Production Luke Grappling Hook in grey on top and an Unknown Luke Grappling Hook in black on bottom. The black grappling hook is larger and really detailed, even more so than the production version, which is why I'm leaning towards it not being a bootleg. The design is almost identical for the most part, except for the Hook and the fact that the Scope is missing entirely. My thought is that it could potentially be an earlier design but I haven't been able to find any information to verify or refute that. I've searched for bootleg figures as well but have not been able to find any that have this grappling hook.
