Boulevard Beaumarchais shops are for people with deep pockets and no patience. Fun and good prices are at the Bièvres photo exchange, held on the first weekend of June.

A Semflex type 31 is a pretty specific request. Even though the Bièvres fair has 150+ booths, and a wider offering than any single brick-and-mortar shop, I would not bet on finding
that camera.
Last year, 10min after entering the fair, I came across a Rolleicord Vb, sold for a ridiculous price "because the cable release socket was broken". I did not bargain. What I mean to convey with that anecdote is that it's best to be flexible and open to opportunities.
Good luck for your search. Below a few pics of Bièvres 2009.
