    4311 = 2212 woofer + 2105 med
    4311A = 2213 woofer + LE5-2 med

    To clarify what you're asking: Are you referring to what appears to be slightly different knobs on the pots? Really hard to tell from that photo but it looks like the face on yours are recessed? Can't say I've seen any like that before, but then I'm not a 4311 aficionado, either.

    it seems that during a period 4310/4311 were indifferently supplied with LE5-2 or 2105
