EVM 12L speaker code

[va3ux]

I have an EVM 12L and it is an OEM type. It indicates that it was built for manufacturer code 836.  I can not find 836 in any of the EIA code listings.  Anyone have any idea who '836' might be ?

Thanks in advance....Phil

OEM codes show who actually made the part (in this case the speaker), not who was it made *for*.
832 looks like a date code : year ending in 8 , such as 78/88/98, the decade is usually easy to guess, and work week 32 (around August the 8th)
