need help identifying vintage chanel pieces (collection, year, model name)

[David Gerloff]

would be nice if someone can help me identifying the 4 CHANEL vintage pieces:
collection, production year, model name, original price.

PIECE NO.1: ON THE TAG IT SAYS - CHANEL // MADE IN FRANCE, 00A // P16217V08854 // AG278 // SIZE 44 // 92% WOOL, 8% POLYAMIDE-NYLON, PAREMENT 100% RENARD - FOX , LINING 100% SILK

PIECE NO.3: CHANEL BOUTIQUE // MADE IN FRANCE, LONG BLACK COAT WITH A RIBBON IN FRONT ON EACH SIDE AT SHOULDERS HEIGHT. Golden buttons saying „Chanel paris“, THE TAG IS DIFFERENT TO THE OTHERS; same as No. 4. - but no Informations on the Tag.

PIECE NO.4: CHANEL BOUTIQUE // MADE IN FRANCE // ALSO OLD, DIFFERENT TAG, LIKE PIECE NO. 3, AND LOOKS LIKE HAND WRITTEN NOTES ON IT// COLLECTION 2/8 // STYLE/MODELE 20804/G49 // SIZE 42 // COLOR 02 // COTTON 97% // ELASTANE 3%

I used to know for sure, and I can't remember where I read/heard it now, but Chanel does have the collection ID in the code and I think P16 stands for Printemps (Spring) 2016 - I think. The other two I don't know, but I recall the important thing to look for in the number is P or A for Printemps and Automne. I assume there are other letter codes for other collections, like Cruise etc. but I don't know.
