What's the difference in lock types?

[Col. Batguano]

What's the appearance, construction, functional and operating difference between the following types of locks?;
miquolet, snaphaunce, snap hance, arquebus

Apart from a wheel lock and match lock / snapping match lock, are there others in the "arcane lock field (besides the dog lock, flint lock, and percussion) I've missed?

Greetings from the "arcane" lock crowd.

For starters, in a self-start mode, mind you, go here and follow the links.

An Arquebus is not a lock type, but rather a short barreled arm of a smaller caliber.

And on an Italian Miquelet the Main Spring presses down on the toe rather than up on the heel as in this Spanish example.

As far as I understand, there is a two different group of locks:
- with the vertical sear;
- with the horizontal sear.

First group was developed later and includes "true flintlocks" (with the frizzen instead of the separate steel and the pan cover) and Italian snaphaunces (with the separate steel and the automatically opened pan cover).

Second group is a way earlier and includes no less than two branches of locks:
- miquelets that have distinction of the frizzen (including Spanish patilla and Italian "alla micheletta", Roman lock and Spanish agujeta, and Arab toe-lock);
- snaplock that have distinction of the separate steel and pan cover (including Scandinavian and Karelian lock, snaplock and snaphaunce).

There is two Spanish miquelet locks: the "patilla" (with the main spring pressing on the heel) and the "agujeta" - the offspring of the Roman lock (Italian miquelet) with just one sear under the toe.
The offspring of the "agujeta" is the Arab toe-lock - the sear was repositioned to work on cock's heel.
