You could look for a Simplex SJ A103 (or for more money and less reliability the LJ 503/523); similar if not the same geometry, and ditto for the triple cage.
One of these - a 223, is braze-on 103 - came on a Peugeot (unknown model, not in any catalogues) being rebuilt, 28-40-52 and 13-30 in the back.
