Lech,

You are not stupid because I can't figure out when your speakers were made either.

Another member asked about lascala's with the following info:

Consecutive serial numbers 1307 & 1308.

I hope someone smarter than me can answer your question.

I have been lucky because all my speakers fall into the 1962-1983.

Danny
