The part number stamp looks okay but I don't see a delco stamp on the front. A photo of the date stamp may help.

 I have a 9204 that was restored in the 80's in my shed collecting dust and the fonts on that one are much larger (1/8" height characters)  than the ones in the picture latecode posted and the date is 334 (late 68), plus no Delco stamp. Interesting the one on eBay has a Julian date of 2 (early 69) and has such a small font. As for the Delco stamp, Steve at Brakeboosters said the '69's should have the Delco stamp on the front shell so the one I have may have had the front shell replaced when it was replated back then -or- two styles do exist. Mine looks like the eBay pic which has no Delco stamp either except larger fonts. The ad states 1/8" fonts but they look like 1/16" fonts. When I bought it in the 80's I didn't know or care about stampings and I traded an 8515 for it! If I had only known back then.....

Below are close up of the rear shell I have from a 9204.

   So based on the samples posted here it's looking like boosters made in 67 to sometime late 68 used 1/8" fonts and those stamped in 69 used 1/16" fonts.
I wonder when the Delco stamping appeared. The 1/8" font 9404 booster I have (made in late 68)  has no Delco stampings. It would be interesting to see if 69 dated boosters using the 1/16" fonts is when the Delco stamp appeared.

My 02D '69 has its original 9204 booster (small font) dated "55", and has the Delco Moraine stamp, inverted, below the check valve hole.

This much seems certain so far based on the few samples posted here:

Boosters made to late 68 used larger 1/8" fonts and no Delco (based on my only sample I have since the 80's from a resto shop)
9204 boosters made in 69 used a smaller 1/16" font but the Delco appearance seems mixed:

1968
Julian date 332 - Delco stamp - no

1969
Tag date Julian date  Delco Stamp?
02D        055           yes
05A        120           no
06A        140           yes
07A        148           yes
  If x77-69z28's  booster is indeed original to his car then that must mean the Delco stamping was not consistent. But this summary is based on a very small sample size so I would not draw any final conclusions. The one on eBay has the small fonts so that seems consistent, but the absence of the Delco can be correct if Delco was not stamped on every unit. However, the ad is wrong in that it states a 1/8" font when in fact that looks like 1/16" height. Also the front cover does not look like a reproduction. Those stand out and can be identified very easily due to them having very crisp pattern edges.
 Give Steve at brakeboosters.com a call if you need a correct booster.

According to Jerry's book the The Definitive 1969 Camaro ... the small stamping started the first quester of 1969.

That's correct, 1/4" characters in '67, '68 and early '69 and then a change to the smaller 1/8" characters in mid 1969.  All '69 boosters should have the Delco in the 8:00 position when looking at the car from the front.
