The problem you have is that most EU/UK suppliers are manufacturers to the trade , of course as usual China will supply you or even India but my trust is low in those directions due to scam calls to the UK from multiple rogue call centers in India which I blocked but it cost me to buy a quality call blocker .
Now there is something !
It took a while but this UK supplier will supply SMALL amounts and cut to size ! -

Most European companies wont supply a small amount unless you try posing as a business --but watch out for the tax man !

You can try these lads - Wiltan Ltd. Cut Core Laminations and these chaps might sell you a few lams, but you have to ask nicely and know what your on about - Motor Rewinds Nottingham | Industrial Rewinds Ltd . But basically it's a case of searching for local ish tfmr lamination makers or whatever near you and giving them a ring if possible.

Both nice links...
But I'd not be sure what grade to buy!
Same trouble with bobbins, I fear. (I'd looked at Asco before and not gone further)

I contacted some tube output transformer and core makers in Poland Portugal but they are not willing to sell or ship ...
Bobbins can be made of fiberglass board (FR4)
And copper wire is easy to get as well

Standard range is silicon steel although if you have the money you can get the ultra high silicon version or NiFe or CoFe but we are talking defense industry standard .
I have tried making with FRP sheet, as I had some limited size strips, but fixing with cyanoacrylate not so good. I intended to use epoxy but...well I got lazy.
Hello.
Any size of the C-core is made by Stalprodukt Stalprodukt SA - wiodący producent wyrobów ze stali, kształtowników i profili made of HiB 0.23mm steel, contact market@stalprodukt.pl. Prices lower than in China, I know because I bought myself.

Though not being 0.3 mm, but 0.35 mm instead, you could ask Waasner (Standort - Waasner), a German company, for the laminations. They do these in VM111-35 aka M6X quality. Be aware that you need to buy stacks of 1000 pc.
Best regards!

Try to ask Arkadi from this (German) site:
Трансформаторное железо с каркасами и креплением для самостоятельного
изготовления звуковых и силовых трансформаторов
Few months ago I bought some 0.35mm trafo kits from him, but It looks like he could have 0.3mm as well.

Look at audio-tschentscher.de - click Zubehör, then click Trafobleche
They have 0.35mm EI-laminations (EI66-EI105) M111-35N = M6 USA - They are good for tube output transformers.
On Arkadis site, the EI-laminations are of the same quality core material. He has bigger cores.
For the exotic core stuff i have no clue.

Hey Kay, click on the link and you will find everything in German. If you can understand it.

I did - and found some inconsistencies there: Scroll down 'till you see M, PMZ, PM etc. I guess the cores in the 3rd and 4th line there are denominated erroneously. I'm only aware of PM or PMZ 114 laminations, not M 114 ones. Transformers with PM(Z) 114/36 or /54 cores use the same bobbins als M 102/36 or /54 ones. The winding windows in the lams is the same with all, measuring 17 x 68 millimeters.
Best regards!
Best regards!
There seems to be a M114 after all, look at the GIVEN winding windows dimension, M102 is given as 61x13,7mm and M114 as 61x16!!!
so window should be 68x23mm, makes sense, no?
