[Collins] KWM-380 low pass filter help

[Lee]

Hello All

Does anyone know where I can get the toroids used in the A2A1 low pass filter board?
I had a look using google and couldn't anything that looks like them I have measured aprox
12mm o/d 12mm height and 5 mm i/d as you know 12mm is 1/2" aprox. 


Thank you.
