Montblanc 224 fountain pen

I found this in a cupboard at my parents' house.
The photos show everything.

Information that can be read from the pen itself:

* Gold cap with 224 and GERMANY MONTBLANC marked on it.
* 750 is marked on the nib.
* The case has minor scratches (but opens and closes without issue).

I don't know much about fountain pens, but I think it's from the 1970s.

As you can see in the photos, the gold cap is tarnished.

The nib shows no bends or breaks.

Please message me if you have any questions. I will answer as best I can.

This is a pre-owned item from a private collection and is quite old. I may not be able to answer highly technical questions beyond what can be seen in the photos, but I will do my best to meet your requests.

Shipping will be via anonymous Takkyubin Compact (a Japanese courier service) with tracking and insurance. The pen will be shipped in its case with cushioning material. Please specify any preferred delivery dates after purchase.

I have had a buyer using ATM payment request a refund and ask for cash payment into a personal bank account, which is against Mercari's rules. I will not accept such transactions.

I welcome buyers who are looking for a pleasant transaction.
Thank you.
