Ronda 5040.D

High confidence

Recorded without the jewel counts and dimensions that distinguish it from the 5040.B, because those figures were not verified against Ronda's data sheet when these records were written. The distinction between the two is real and is documented by Ronda; it is simply not asserted here on the strength of recollection.
