Looking for a catalogue of Latvia stamps starting from 1919

[Daniele]

Hello, I'm an italian collector of stamps from Baltica states.

I'm searching for a catalogue of Latvia stamps ecause in a lot recently purchased I found many stamps with partial perforation. I mean stamps with one to three sides with pers and one without perfs. These stamps belongs to the ordinary serie printed starting from 1919 and successive years. My question is: does it exist a catalogue printed in Latvia classifying the varieties?
Thank you for your understanding.
