[Leica] SEI exposure meter

[cmbrow@mail.wm.edu]

Here's a toughie, but someone on the list may know.

I want to have my SEI .5 degree spotmeter recalibrated.  I need, as 
well, I think, to replace the internal reference bulb.  Does anyone 
have a clue as to who might be able to do this?  The meter's about 
thirty-five years old, but still seems pretty tops for what it does.

Ilford used to disribute Salford Electrical Instruments, but that was 
before my time.

Thanks in advance.
