[OM] NiCad Battery Pack M 15V Control 1

[JUANITA M. ALMEDA]

Does anyone out there know:

1) Who sells replacement batteries for the battery pack used on a Motor Drive 1?
If not, can you advise me where I can buy them in the US?
 
2). Do you know of any lens multicoating restoration service in the US? One of 
the elements in my OM mount Sigma 500 mm lens has developed a smokey white 
layer on the lens. I am hoping that restoring the multicoat will solve the 
problem.

Thanks
