The French illustrated catalogue for 1928 is available from me on CD-ROM for 3 post paid. It has around 270 pages; here are some sample pages.

The 1930 version is even more extensive, running to about 340 pages. I have made a quick comparison of the main numerical series.

1000 series: 1928 last No. 1154; 1930 1226

2000 series: 1928 last No. 2055; 1930 2099

3000 series: 1928 last No. 3008; 1930 3043

4000 series: 1928 None; 1930 4000 - 4029 inclusive.

5000 series: 1928 last No. 50001; 1930 5004

10,000 series: 1928 last No. 10198; 1930 10199 plus 10078, 10098, 10099 which do not appear in 1930.

None of this takes account of any numbers that may have been dropped from the catalogue.
