New purchase! (and questions): 5513 Sub from 1974

[zimen]

Hello all, here’s my new purchase. My first vintage piece! I’m a really happy owner of a 1974 Submariner 5513 serial 379...

Here are some pictures below.

And I have a couple of questions for you if someone would help me :)

First of all an opinion on the overall watch and condition. If you think that there are any problems with it. I’m not an expert but I already noticed that the clasp (Or entire bracelet) is from 1984 (marked “i4”). I also believe that the bezel is a later one because the font and markets seem too thin, correct?). Shouldn’t this watch have a “fat font” bezel?

Also, it didn’t come with box or papers.

Do you think that I should source the period correct parts for it, including box? And if so, would you help me know which are the correct parts?

Did this come with a 93150 bracelet or the 9351? And is the correct box the 67.00.3 or the 10.00.1?

Thank you in advance for your help.

Simon
