T-310

It appears that the pressings with a T-310 on the LP sticker are the last pressings, though I'm not sure what that means in terms of dates exactly.

These have a 'D' in the matrix (as do some of the TS-310 pressings) which should indicate a fourth (or fifth) lacquer and thus a later printing.

But no dates exist (that I am aware of) for the production of these lacquers.  According to a source at Motown, info on the pressing plants are long lost in the purchase order files that disappeared over the years.  Unless someone happened to scavenge them as the Donovan (home to the Motown offices after the Hitsville facility was outgrown) rotted away, these are lost to history.

Considering that this was a big selling album it's quite possible they all came out in a short period of time in order to meet demand.

There is no mark in the run out groove that indicates a particular pressing plant.   As far as the information I've gathered it was stamped at Dixie Record Pressing but I have yet to find any detailed information on that plant online.

The Tamla label also has a brownish tint to them compared to the usual light grey in all the other pressings.

The T-310 pressings are the only ones that have DeRouen spelled wrong.
