Info Wanted - Bridgestone Folding Bikes

RideTHISbike.com reader R. Juniper is looking for more info concerning a Bridgestone folding bike that he now owns. He writes...

I am the owner of a Bridgestone Folding Bicycle. Don't know too much about it, so, I'm looking to someone for help.

Serial No. F231311, I think this number is the production number 3032, and a model Picnica, 3 speed, made in Japan. Very nice folding bicycle, easy riding, very good for a man of my age.

Any help you can give me would be most appreciated, date of manufacturer/year, etc, etc. One small feature is it has the generator mounted near the rear wheel for the head and tail lights. Can't find anything on Google about this model, except for minor details which are of no help.

If anyone has more info, feel free to post a comment.
