vintage Seymour Duncan sticker codes?

[Jaik]

I got my hands on an old Les Paul with some very old Seymour Duncans in it.

One is a No Logo 59b , the other is a logo SH 1N ... but what do the rest of the codes on the sticker mean ?
IHK30 ? and 0064 ?
any idea when that was made?

I hear the no logo SDs like the bridge pickup here are particularly sought after? Is that a thing?

What do I have here? Thanks !

59 bridge from around 1977-1978
59 neck from after 2002 up to 2010? (doesn't have date code, can't remember when they started putting date codes on, thought it was around 2010?)

59's dont have logos. some people do prefer the old ones though

Your 59B has Philips screws so i say 1978 to 1980, the slotted screws were from 1976 to 1977.

I appreciate the responses thanks ! What do all those other letters and numbers on the SH 1N mean ? IHK30 ? and 0064 ?

I don't think its likely to be as recent as 2002 as the previous owner was in his final years towards the start of that range, i suppose not impossible but it would be surprising.
Thanks!

Just non public production codes.
