Actually I have gotten these numbers from your post:

But it seems to have some errors, I believe the correct numbers are:
- Ref. 47151/000P-8917 in platinum (10 pieces),
- Ref. 47151/000R-8918 in rose gold (30 pieces),
both with rose gold-plated skeleton movements.
- Ref. 47152/000R-8918 in rose gold (10 pieces),
- Ref. 47152/000P-8917Β in platinum (30 pieces)
both with rhodium-plated skeleton movements.
