Also, people have been talking about the differences between the super classics and standards, and some people say that the shells are the same, just the hardware, the badge and the wrap are different. Thats true - BUT, i'm not sure if everyone knows this, but on the super classics, the bass drums were drilled for 20 lugs, whereas the bass drums on the standards were only drilled for 16 lugs.but yeah - most importantly PLEASE put up the serial numbers on your Ludwig Standards, as well as the date stamps!!!
No, the Standard bass drums are not drilled for a different lug count. The 22" have twenty lugs, the 20" have sixteen. At least in the original runs, from the late sixties. This could be true about the later ones.
The kit I have is a good example of the shell swapping Ludwig did. The snare and one rack tom have the classic white painted interiors. The rest are the normal Ludwig Standard granitone paint. This proves they just grabbed the shells and wrapped them in LS wrap and applied the LS hardware.
Poppy79424 had a very informative series of posts about converting Standards to Classics here:

While his post detailed the conversion, it also gave a very detailed explanation of the differences in the two models of drums. I think these were early runs of the Standard line as well.
I think I sent the serial numbers on mine in to the forum already, but I didn't ever check to see if they got posted anywhere. See mine by clicking on the link in my sig.
I'll dig out the numbers and date stamps and post them here over the next couple of days.
