"Typ Leipzig" - I'm looking for informations

Hey,

I'm writing an article about "Typ Leipzig" buildings from VEB Metalleichtkombinat and I'm looking for informations about this type of building. Maybe have you any catalogs, brochures or articles and could you make scans for me?
There are a lot of "Typ Leipzig" here in Poland. Probably It's more popular than in Germany .

Thank you in advance!

Regards,
Adam
