Dating modern Guzzi components

[v65tt]

Managed to pickup another v7 stone engine and box for my other TT. Im curious to try and date the components and found these markings

Intrigued...

10/11 2009???

It's a gearbox from a single throttle body v7 so must be 2013 ?!

The braille dots must be part of the clue...intriguing indeed!

Casting numbers.  Could mean date, shift, machine, etc.  Most manufacturers use them for lot trace ability.  When it comes to the date could be Julian, or week #, what ever system that supplier uses.

You know, there's a lot of dating websites on the interweb you could try.

No, seriously (as much as I ever get) all the numbers are under 12, which makes months a possibility. Likewise with being under 31.

Those kind of devices can either be made so they can be reset on a yearly/monthly/weekly/daily/hourly basis ( a chore, but for some products it's appropriate ), or they can be artifacts of when the mold was manufactured.

No, it was supposed to be mold number 11, but it took Luigi a couple of tries to get it right!

I lack the Guzzi history knowledge to know when that mold should have been run based on the components that came out of it.

So I'm the perfect person to speculate that it was used for a couple of different run lots in 2009, a couple more in 2010, and then three times in 2011.

It doesn't seem likely, given the low volumes, that it was run that much in September-October-November.

Supposing the dots represent a month of the year based on clock position:

So 11th and 4th month of 2010
11th, 1st and 5th month of 2009
11th, 12th and 1st month of 2011

Just another guess...
