I'm working on the Narcissus harpoon gun from the end of Alien. I've modelled most of the add-on parts as well as I could from the limited reference, but would much prefer to use the original parts. Many of them look like kit bashed parts (excluding the tape deck buttons) so I'm hoping some of you guys might recognize some of them.
These are two different props. Depending on what parts turn up, I might make mine a hybrid:

Also there are these model kit parts on the control panels, might give clues to the parts on the harpoon gun?

Thanks
