Nah. They're from South America.
I have no clue about 'foreign' sheeps, only the British ones. Although in a sense the concept of breeds and improvement of them for various characteristics is really an Agricultural Revolution type concept (post 1750, England then colonies of). We do have some more or less unimproved primitive sheepies like the Soay, etc but not fun to spin or learn on.
Re. Winghams I think the only spindles they stock are modern Ashfords. Clunkers and too obviously modern - plywood and big obvious logos etc. You want to aim at something round about 25g. Is it top whorl or bottom whorl? I have some Middle eastern antique whorls I got on ebay - they are often a fraction of the price of modern spindles and you can mount em on a shaft easy enough. (My favourite is a Roman soapstone one - probably cost me all of a fiver).
Top whorl is easier to learn on. One nice maker of top whorls is Karen at

I'd suggest rather than specific 'breeds' you find out the broad characteristics - is it long wool or short wool? Lustre (shiny) or dull? Length of staple? That kind of thing. Then just look for a modern equivalent. Winghams have the broadest range but it's processed stuff. But anyway if you can find the general 'type' you need, go with that.
I have an unending supply of Hebridean fleeces - again, obviously British but very 'primitive' in terms of type. If you should need any in future, message me. Farmers can't give the stuff away right now. If you can get raw wool you can pay nothing or next to nothing for it.
What about silk? Again, I only really know about its history re. import into the UK, so not sure how early it got anywhere else, but Google is your friend.

Also - linen?
Really no one is going to do fibre analysis so you only need to find the broad characteristics then reproduce them with something locally available.
Which means you may need to pin down preparation - carded = shortwools, combed = longwools but again, carded and combed are things relevant to Europe, not sure about elsewheres.
A distaff is easily achieved - any forked stick stripped of bark will do. Of course it's only of any use to you if you're doing it from combed fibre anyway, or something arranged to be spun 'worsted' as if spinning from rolags you can dispense with it.
There are some lovely, helpful groups of spindlers on
