Back in the day they (or their 88mH cousins) were the inductor of choice for building home brew RTTY terminal units and other accessories which required high Q tuned circuits in the audio freq range. 

Still have a few in the basement along with the Creed teleprinters.  

End of nostalgia moment.

Anyone know what these were used for? 44milli henry  (44mH) Inductances made by Hatfield Industries Ltd. 1981 NZPO order number H8959. They are in a plastic sleeve with between 17 – 20 per sleeve. Something to do with NZPO Telephony back in that era? Are they any use to anyone (free to a good home!)
