Here is a quote from John Franklin's book: Admiralty Ship Models 1650 - 1750.
It describes the gratings that were made on Admiralty models at the indicated times.
The book describes the Admiralty models from museums built in those days.
Here is an extract from the book specifically about lattices:
Slotted holes in deck grilles continued to be found on models until the late thirties of the eighteenth century, but from the beginning of the said century, from about 1720, composite deck grilles are more and more often seen on models of higher quality workmanship. This method differs from the method common. These "true" deck railings are usually very intricately crafted from thin longitudinal battens recessed into thicker transverse ledges.ly used
today's modellers, which consists in connecting de-tals
half recessed into each other, which not only does not correspond to historical reality, but is also more laborious.
