This is a padlock that came with one of my 1960s sets which I believe to be the original.

To give an idea of scale, the keys are about the same size as a suitcase lock, but the padlock is a bit bulkier than today's luggage locks.
Thanks, Anthony, for pointing this out to me.
I remember this crackle red finish now. And think I have an old socket box in this finish somewhere, I'll have a rummage soon.
What confused me was when 'crackle finish' red was mentioned, I immediately thought of the black finish used on e.g. some MG dashboards, steering wheel mounting bosses, etc. Was this 'crackle finish' or 'wrinkle finish'. (I suspect it is 'wrinkle').

Good find, and usefully available in a range of sizes as well. They're not quite right - the Britool lettering is a bit bold, and the bits round the outside are a bit skinny. There should also be a black border round the outside as below:

The crackle finish boxes had riveted on aluminium badges - the stickers were an economy measure introduced with the red hammer finishboxes. I have wondered about the legality (in respect of rights to the name) of having a some made by one of the chassis plate replica manufacturers, but I only need a couple so it didn't seem worthwhile.
That's what was confusing me - some people call it Crackle, others call it Wrinkle, others call it Crinkle!
I did a bit of a search and found a site discussing Crinkle/Wrinkle paints and how to make this effect occur using 2 different types of paint applied one over the other. (www.finishing.com/0400-0599/409.shtml) It seems one of these techniques could be used to make any shade/colour you want. There's also mention of using an oven to cause the reaction to occur ( a bit like stove-enamelling?).
VHT do a wrinkle paint in RED but it looks a much lighter shade than used by Britool., it's more like what Ferrari used on it's camcovers (i.e. Testarossa) so similar to MG dashboard finish, idk if this would be the same as Britool Crackle Red.
Anyway, it's available from Frost and Co. in the U.K. or on Amazon. (This VHT brand may have been referred to earlier).

I have to confess I only found it by doing a Google search! The finish on the Britool boxes is smooth. I know the textured finish you refer to on MGs etc and I'd agree with your description of wrinkle finish, but i have often seen it referred to as crackle finish as well.
I haven't yet found anyone selling a product to reproduce the finish on the early Britool boxes which is a shame as I have an early Tractor Service Set box which is still in daily use and in good condition other than the lid which from the paint has almost completely worn off.
The original crackle finish I believe to be stove enamelled - even the plain red finish inside the box is as hard as nails whereas the slightly later Universal Service Set box I bought in a mad "I must collect everything Britool" moment has the hammered finish which is brittle rather than hard if that makes sense.
See post 28 - the outside is a crackle (NOT wrinkle) finish.
The closest I've found to the solid red used on the inside of the boxes was a RAL shade available in a Rustoleum aerosol. I'll look it up and get back to you. From memory it was a bit orangey, but near enough so long as you didn't have an original next to it.
That's a very interesting thought - I know the local powder coater fairly well so I'll ask the question after the Christmas shutdown.
I am not certain but it may have been supplied by Carr's paintsThat's a very interesting thought - I know the local powder coater fairly well so I'll ask the question after the Christmas shutdown.

Very nice. I can't get over how they and Williams pretty much had the same design for the sliding t bar.

On the crackle finish subject…
If you're interested in trying...
The process:
You are essentially applying three coatings to the case: paint (base), glue (crackling medium), and paint (layer that crackles). The first coat is put on and let to dry completely. The crackling and the top coat are put on one right after the other, but in very small areas (2 or 3 square inches) at a time.
(1) Apply the base coat. (Looking at fanders’ wonderful example, it looks to me like red is the base coat and black is the crackle coat.) Use something with high-gloss that will dry hard. Let it sit for days or longer. Make sure it’s truly dry.
(2) Using standard white household or school glue (I used Elmer’s, which is a very common brand over here…), apply it in a small area. Let it start to dry, but don’t let it dry completely.
(3) As the glue is drying (tacky, sticky but no longer wet), apply the top coat of black paint right over the top of the drying glue. As the paint contacts the glue and the glue dries up completely, it dries up the black paint with it. You will see this almost immediately as the paint is applied and it will continue as the glue dries completely, leaving non-uniform cracks.
One thing to keep in mind is that the paint crackles in the direction of the top coat brush stroke. Unable to find a photo or surviving example of a single original Blackhawk Q.D. case with a crackle finish, I was going for a sort of wood-grain/alligator skin look. So my brush strokes were long and linear. If you want to do the effect shown in fanders’ outstanding example, I think you would need to use a sponge or a rag or something like that to dab it, or even twirl it. If I were doing it, I would find some sheet metal or old castaway boxes and experiment until I achieved the desired look.
And if you'd rather not, I won't be offended.

I wonder if they might be BA (British Association) threads.
7BA has a thread outer diameter of 0.0984 in. (only 6 thou. larger than your measurement).
Can you measure thread angle and threads per inch (t.p.i.), possibly using a thread profile gauge? ( if you have one). BA threads have a 47.5 degree thread angle and the t.p.i. won't be an even number e.g. 7BA is 52.91 t.p.i.
Iirc new screws were supplied with ratchet repair/rebuild kits.(back in the day).
