Solved -PJ456 - 1 month 1 week and 1 day.

According to my sources there is at least a big relation to another manufacturer, but not German.

It is a 1932 Mistral with a Ballot engine

[Paul Jaray]

And it's correct! 
I'll award the points soon, I'm waiting Allemaon's reply about his guess.
Starting from TOMORROW, past 06:47:57 AM everyone can have a go on the final bonus point!

My suggestion for the meaning of the title is that 1 month 1 week 1 day is the length of time it would have taken for one single puzzler to answer all the questions according to the rules.

There were 39 answers, and at one answer per 24 hours that's 39 days = 1 month, 1 week and 1 day!

1 Month, 1 week and 1 day is the amount of time a single puzzler would need to give the answers to all 39 questions respecting the 24 h time lock after each answer.

There's something strange I don't understand going on here!
You say "It is past 6:47:57 AM now" but your post is timed "10:48:06"!

I posted my reply at 6:48:21 AM, half a minute after the time limit set by PJ!

Any ideas?!

[Wendax]

I have 6:48:06 AM as the time I sent that post:

I just found out that you can change the time offset in your "Look and Layout Preferences". I didn't do it, but you probably did.

[Paul Jaray]

I'm afraid you are both right.
I should have written "24h after Reply#151"....because I think you have set 2 different timing on your PC.
I left the one I found here (07:51AM right now but here it's 01:51PM).
This is the right conclusion for this puzzle! 

There won't be the (already in progress) #2, I swear.
Point for both of you.

Yes, my computer shows GMT; you have US eastern time on yours?!  No wonder there's some confusion...!
I did wonder what you were doing at your computer before 7 am on a Sunday morning but to be honest I didn't look back and question it; I was not so surprised...!

Thanks PJ!  Very fair.
i hope you change your mind about #2!  That one was fun.

Mille grazie.
I think the "time lock" idea is a good one for interesting, but not so difficult group puzzles, in order to make them safe against guys like me
