78-Bahrain 1993 mc rear samples

This is part of a batch of Bahrain 1993 series rear motorcycle plates and are all samples. Again low 3 digit numbers feature prominently amongst the samples.
All 1993 series mc plates were blue on white and some of these are black on white. The Arabic number is always above the western number and some of these are reversed. The plate 0000 is typical of the last plates that were sent to collectors before Bahrain stopped giving plates to anyone.
