Dating Vintage Kaweco, And The Numbering System

[siamackz]

I just bought three vintage Kawecos:

- 83A 07

- 803

- 805

 

I tried doing some research online but I can't find much info on the pens. Does anyone know:

 

1. How does the numbering system work? Like the old MBs had a system where xxx would mean tier+filler+nib size. For a Kaweco what does 803 or 805 mean? What does 07 at the end of 83A 07 mean?

2. How can I date the pens? What indicators do I look out for?

 

Thanks all!

I forgot to mention that all four are 'Dia' model, and they have flat cap tops.

PM Kaweco, a forum member, his grandfather I believed worked there and he is a scholar of Heidelberg fountain pens. They were then made there.

I suggest having a look at the old adverts on the http://www.kaweco-pen.com/en/Info/download-service/01_antike-werbung.php

 

The 805 and 803 are likely models from the early 50s.

 

83A is from the late 30s or early 40s. I think that the 8 was used for upper models, while the 3 stands for the smallest version (5 and 7 designate the bigger ones). The A in my opinion stands for Alt (old). The O7 is a designation of the nib size but I can't remember whether it stands for a double broad or fine oblique.

 

I may be wrong though.

 

Anyway, it seems like a good buy!
