Many thanks to Terry for his generous contribution.

They are are on their way. The blue is a middle blue. I think it came from the high beam dip switch as it still had connectors on its. Hopefully it will suit the purpose.

light blue, blue like the header ,but not like the minimania logo on this page.

It looks like I have them. The brown may be heavier gauge.

Ok let me check on the other colors, if this one will do.
Dark blue or light blue?
Terry

Terry, That's the one. It's about 1/16 thick OD. The Blue, Red, and brown are about double the thickness. Jim

I found the purple with orange but it is only maybe 9 inches long with the connectors.
It is very light gauge, maybe 20?
I can probably come up with the others, if this will work.
Terry
PS: It looks pink in the picture, but is closer to orange.

Thanks for all the replies.  The widths were an eyeball estimate of the vinyl widths. A board member gave me a partial front loom of an 67, but no good on the colors. This is a modern mini 94 vintage. I am installing a new fuse board to get rid of the torpedo style fuse holders and need to lengthen a four of the wires. 

If no one comes through, I can buy from British Wire. Thanks for that recommend. 

I'm still interested in recycling. Jim

I've got them either as new modern thinwall (17A) or hacked out of a loom.

I'll wait and see if anyone Stateside can help before chopping.

Sorry, I don’t have what your looking for. What I have is under hood and firewall, dash area. No colors matching your desire in 62. Can post photos if you ask.

6464 /jim ding... I have a wiring harness out my mini pick up truck if  you it .. as I went with a New  universal VW wiring harness..  later bc

Sorry, But I do not have any spare wire at this time. As you probably already know, most older British cars, use the same color wires for the same circuits.  Check on line for  "British wiring color codes". 
I have been able to find, most any wire I need, (short pieces), form my local "u pull it yard".

I am sure I would have what you need, I saved a cut up harness from a 62 mainly for connectors, your measurements are for the outside of the vinyl? Will post back when I am sure I have what you need. Cost would be just postage.

British wiring will have what you need Jim.

Hi guys,  I am looking for some short pieces of wire from a mini harness. About a foot each will do.

Thin gauge (It's about a 1/16" wide)  Purple/ with orange stripe.

Normal gauge (It's about an 1/8" wide) Red 

Normal gauge.                                    Blue

Normal gauge.                                    Brown

Gladly pay. Working on my mini's loom. Thanks Jim
