Pattern Numbers were odd, numeric part numbers used to name various pieces of naval equipment.

I do not know what authority created or managed the use of such numbers, or even whether they were unique; if there were a Pattern 50 light bulb, could there also be a Pattern 50 torpedo director?

No matter... this being a Wiki, I think I will make an anal retentive table of some of this data.
