Hey I can get some Norma Hellas Deca with the lot numbers:

#13870 EXP: 8/05
#17550 EXP: not sure as this part came off with the packing tape....

Also I can get some duratestons with lot numbers:

#13136
F: 11/2002
V: 11/2007

#12106
F: 9/2002
V: 9/2007

The duratestons info looks like it is the same ink as the rest of the screening on the amp. This is a bluish color screening....Also they have the red ring at the top, then a yellow one and then the blue ring at the neck of the amp.

The deca's have the Norma Hellass.a. symble and wording screened onto the bottle underneath the lable in a blueish color. This seems different from the last norma I had with a white symbol and wording underneith the label.

Can anyone verify these numbers and from the discription I have given tell me what you think?
