When is an Osmiroid 65 Mk 1 not an Osmiroid 65 Mk 1...?

[mrick]

It looks like a 65 Mk 1, but then you notice that it does not have a lever, is engraved "Property of EG Perry Ltd", and when you dismantle it, you find there's a cartridge in it.

I assume that it was not a production model, but a prototype, but I would appreciate any suggestions as to its identification. I also wonder whether there is any cartridge that might fit it, as it would be nice to actually write with it.

Photos would help, but why not try refilling the cartridge?

Osmiroid and Platignum are brother and sister if you will. The 1970s vintage Platignum cartridges I found recently buried in the back of a drawer are the same as short International cartridges. With that, my expectation is that a Diamine cartridge will fit you Osmiroid 'almost a 65'.

Thank you both. I will follow your suggestions, but the identity of the pen remains a mystery...

I'd still like to see a picture...and I'm working on my own Osmiroids today.  🙂

But I long suspected it. And of course, they are also very close relatives to Esterbrook.

Does the pen resemble this?

That's clearly either mislabeled, or it's a lever-fill 65 that's been altered to accept cartridges. You can see the lever in one of the pictures. I honestly can't see how a cartridge would even work in such a beast: the old-style Osmiroid/Esterbrook nibs don't have anything to pierce a cartridge end with, and the actual cartridge Osmiroids I've seen have very different architecture, both aesthetically and mechanically.

@mrick…does the pen have a nib unit that threads out, or is the entire section threaded?
