Complete Classic Symbols Set

More complete classic dungeon symbols catalogue.

In other words, including more symbols for the likes of levers and cranks, trap triggers, etc. Attached is a copy of the Basic D&D one from the 'red box' in the 70s which has since been the standard approach. Some of these are already included in the catalogue, so hopefully with a little work the set can be complete. Thanks in advance for supporting! :)
