I must be the only left-handed Sigma Anniversary owner.

I bought it in Brussels about 1981 and it was professionally modified by the shop's repairer to reverse strings for left-handed playing.

It has a "10" stamped next to the described stamp, Anniversary insert and so on.

It's still a wonderful instrument. I use it from time to time to play classical music on it.

Just, I realy wonder if there were only 100 of them !
