Slovenia/Yugoslavia 1919/20 Question (Chainbreaker)

Hello everyone,

I recently purchased a small but nice collection of 1919/1920 Slovenia Yugoslavia stamps. Chainbreaker etc.

It is divided into different printing types, different types of paper, different colors, different kinds of perforations etc.

My question: Is there a site or reference book that gives good information on these stamps.

I mean good information on types, paper, perforations etc. It is not about value, it is about knowledge.

Thank you for your help.

Some examples from the collection.

As a starting point is this article:
https://www.stamp-collecting-world....SL1919a.html
For specialization the article recommends the Michel catalog for Yugoslavia.

Listed below is the old specialty handbook. It is a dual-language book in German and Serbo-Croatian. It is printed on wartime paper and usually is in poor shape.

Dealer Phil Bansner (USA) has it for sale.

Fleck, Vladimir. PRIRUCNIK MARAKA JUGOSLAVENSKIH ZEMALJA - SLOVENIA. Published 1940s/1954. Card/4 vols. LL. 844 p. Illus., many enlarged. Handbook of Slovenia.

The best place to start would be the Stanley Gibbons Europe 3 catalog .It is more detail than Scott catalog .

There is a Slovenian web site on these stamps by Emil Hudomalj .
Must use google translate or something else.
It is an introduction, but there are some tables on perforations in ZBIRKE V ŠTEVILKAH ,click on posebna tabela.

There is a partial catalog on picclick at the moment...

The Michel Suedeuropa catalog illustrates the difference in the 2 "chain breakers" issues, and it lists numbers issued, but it is not a specialized catalog for this area.

Can someone beat this record ------Here is my CHAINBREAKER album page from over 52 years ago ,This was before the Scott specialized catalog came out and I was just out of high school when I worked on these .

You asked and you shall receive. This is definitely among my favorite sets of stamps. The drama and the colors and the history all come together to make what is quite possibly a perfect stamp. There's also plenty of errors to be found!

Here are mine:

I would like to thank everyone for their thoughts, suggestions, links and pictures. all of them very usefull

Seems like this is a series which has many fans and a level of depth that at first you would not expect.

Now it is up to me to check and verify the former owners work.

Thank you,

Johan.

Hold up Johan ,let me put up one more thing that will help you check what that previous owner wrote up .

Here is the pages from the S.G. catalog ,these are the best to use for English info.
