Mystery Parts #1

I have begun the tedium of soaking, scrubbing, and polishing nuts, bolts, and other hardware, one bag or box at a time. The first bag I did today had a label, though the text was illegible, so I have no idea what these parts are for. Hopefully the Moss or Victoria British catalogs, service manuals, and my friends at the British Car Forum will be able to help me identify them.

Here is the lot after cleaning (sorry, I was a little ahead of myself and forgot to take the before picture):

The three half-inch bolts have some head markings as seen here:

I am guessing that this means (SAE-type with Right-hand threads). Also, I don't know if any of this hardware is original to the car.

The other curious piece in this group was the washer below:

Your guess is as good as mine for this guy.

I have many bags of small parts to go, but I feel like I have actually begun the project. I also started a spreadsheet of every part that exists (or should exist) on the car, whether I have the part, what the current condition is, the price for a new replacement, if I think I can restore the part, etc.

I'll continue posting individual things as I clean them, and I will make sure to post a few before-and-after shots for dramatic effect.

And by the way, my new Dremel is AWESOME and make cleaning the little parts a breeze.

Update: The pins are clevis pins that may be for the clutch pedal assembly or the hand brake. Bolts may be for either. Still no idea on the notched washer.

Update 2: Second vote from BCF that most of these parts are for the hand brake assembly. Also, the markings on the bolts are evidence that they are British bolts, but have nothing to do with type, size, thread pattern, etc.
