Tamiya made 750,000 Sport Tuned?

[Juggular]

I found an old box that I kept. It was from October 2019.  The new one is from May 2025.  Increasing number made me suspect that it's a production number.  

The difference is 147,254 in 240 weeks.  That's about 613 a week.  Google says Japanese manufacturers work 6 days a week.  So that's about 100 a day. (I'm sure that's not all they do, since there are dozens of other motors.) 

The Sport Tuned motor was introduced in October 1990.  1513 weeks between then until October, 2019.  That's 392 per week or 65 per day (on a 6 day/week work schedule).  Sport tuned wasn't as affordable as it is now, so maybe that tracks?  Obviously, it's possible that I could have gotten an old stock in both cases and the actual number now could be 900,000.  But if these are close to average numbers for the year of purchase, maybe these are manufacturing numbers?  Either way, it's not important in life.  I just thought it was interesting.

Correction, Tamiya put 750,000 Sport Tuned stickers on Mabuchi motors.

I wish they would go back to making them in black.

I just checked an approximate 10 year old sports tuned box and it doesn’t have that number at all.

There are no such numbers on my Sport Tuned box either.

I think it's a more recent thing.  My GT-Tuned motor boxes (motors bought in the last couple of years) have batch numbers too.  Older motors I own don't have them.

No numbers on my boxes either
