Tnx to all who replied on this subject.  BFI seem to be the preferred UK 
supplier for micrometals.  I actually need some of the smallest cores T20-2 or 
similar for a bank of sixteen 11th order elliptic filters for multiple anti 
aliassing filters in a digital receiver.

Unfortunately some US companies only use Fed Ex to deliver overseas which puts 
on a ridiculous surcharge.   Recently I wanted some 6GHz divider chips from 
Hittite Microwave - which could be ordered via their web site for $5 each, with 
no minimum order charge.   Got to the bottom of the order form - and FedEx 
delivery was compulsory overseas with a $99 charge. So I just  bought them from 
an individual who keeps a few specialist chips for the amateur market and paid 
?9 each for a higher frequency 13GHz device instead.

Ordering by credit card from the US is fine for private purchases, and probably 
for those in small private companies, but here we have to go through tortuous 
purchase ordering processes from approved companies - so that 'public money is 
not wasted'.   However, I have used my credit card and claimed back the 
expenses before now where 'speed was of the essence'

The main UK  importers are BFI Opilas at Milton Keynes. But beware minimum
order values if they are not in-stock.

I have the -2 material in   200   157   and  92  dimensions
I also some of the -3 material in 130 and 157.....But it's quite 'lossy' at
LF and probably unsuitable for 136kHz.

All cores can be ordered on line from Amidon in the USA with a credit card
