Last count it was getting close to 400. Just send me the chassis number or VIN number and i'll tell you if I have them recorded, or if I have partial ID already. If you have non-Sandmans (especially those with original engine) I record those too, primarily to fill in info gaps. Either by chance or that is how they were built, I have big clumps of numbers of Sandmans and then gaps in the ID, so the non-Sandmans can help to assess Sandmans that fall into those gaps (looking for non-matching ID plates, faked plates etc when people ask me about what they have found).
