hello mr zygmunt_s,
i do not have as much info on these units as Yidneck does.
you may want to try and contact him, he may have what you're looking for.
As far as trying to contact me? your emails must have been going to my spam box, usually i may scan through it but i get alot of spam so i may have deleted them by accident, sorry about that sir :o).
