[ARC5] Wanted: 285 KHz Crystal

[J. Forster]

I'm looking for a crystal for a friend who is not on this list:

It's single FT-240 size crystal that has a frequency is 285.00 KHz. This crystal
is used in the Crystal Calibrator No. 9, which is part of the British Wireless
Set No.38 Mk III. This calibrator is an external bolt on unit that attaches to
the side of
the case of the set.

I hope that will give some one enough information to identify the required
crystal.

Thanks in anticipation.
Keith.
