Hi, good morning, as a paper and book conservator, I have some knowledge about leather. In Portugal there is an history of producing it, specially in Alcanena.
I might help in this matter if you are interested.
I found your topic is very interesting and very new to our reserach field. I am trying to find out about the leather industry in my country first before contact you again. i hope for future collaboration or may comparative study between Malaysia and Portugal
