Help with Sanyo DATE CODES for Magazine Article

[xxxmain]

Hi everyone, I'm compiling a 'History of RC Batteries' article for Velocity RC Magazine and I could use some of your help.

The article is basically done but I'm trying to narrow down the dates of release for some specific cells. There is very little info on some of the older cells so I've decided to use Date Codes to get some info, which is where all of you come in. I'm trying to find specific release dates for the following cells:

Sanyo 1200 SC (yellow shrink)
Sanyo 1700 SCE (yellow shrink)
Sanyo 1200 SCR (red shrink)
Sanyo 1400 SCR (red shrink)
Sanyo 1700 SCRC (black shrink)
Panasonic P170 (date codes won't help here but someone may know the release date).

Would everyone who has old cells laying around please check your date codes for any of the above cells and post them here? The date codes are the two letters printed on the side of each cell. For example, I have some old Sanyo 1200 SCRs with a date code of SD (S is 1988 and D is April). I'm looking for the earliest code for each of the cells above. If enough people post codes for specific cells I can get a tighter window as to the release date.

For those interested, the date codes are alphabetical with the first letter being year and second being month:

First letter - R=1987, S=1988, T=1989, U=1990,...... etc.

Second letter - A=Jan. B=Feb. C=Mar.... etc.

I've got a few date codes already but I'm looking for the earliest ones printed. I figured this forum would have the largest collection of old cells to reference. So please, everyone with old cells listed above, please post your two digit date codes below. No pictures needed, just the cell type and code. For anyone who contributes, I'll hook you up with a free current issue of Velocity RC Magazine as well as the next issue which will contain this 'History of Cells' article.

Thanks in advance for the help!
