Yes, more info on AK LE would be great. I do not know what sort of serial number system was used on those. It is possible they started at -30300 and went up from there, since regular AK serials only go up to -90209 or -00300. So -30308 would indicate PCB number 38.

BTW, on a somewhat related note I have seen Mushi Matsuri 1.5 serial MHN-20005, so we know at least 25 were made.

There's also this: http://collectedit.com/collectors/shou-time-213/arcade-pcbs-281/mushihime-sama-cave-festival-ver-1-5-japan-by-cave-31982

It appears to be a Mushi Matsuri V1.5 with serial 3970 (or 3920, hard to tell), indicating a Matsuri version converted from a regular Mushi.  So apparently there are more than just the MHN- serial numbered boards.

I've noticed something interesting about Akai Katana PCBs. The first 100 or so appear to be freshly made PCBs. See, for example, this PCB from tops (serial AK-20002, which means it was the 22nd one made):

https://www.tops-game.jp/products/detail.php?product_id=5499

Only one date stamp on the back, and the date stamp is from August 2010.

However, mine and two others I've seen with the RUN number 2 (e.g. AK-XX2XX), including this one currently on YAJ, are clearly reprogrammed DDP DFK PCBs, because there is a date stamp from May 2008 and another from August 2010. Anyone have one with a RUN number of 1? Basically, I wonder when they started reprogramming older PCBs to fill in the AK production.

EDIT: I see forum member Monouchi's PCB has a RUN number of 1! Hopefully he will let us know how many date stamps are on his PCB.

Thanks for checking! So, it is just like mine. And now we know they started reprogramming DFK PCBs beginning at least at the 175th Akai Katana PCB.
