Hi mates!

I hope to don't bother with my request but:

Someone know when the first J made their debut in frontline units in ETO and PTO?

I have try to search in my reference but I have find no date of this!

I'm asking this due my need to know the transition time for frontline machine from the oldest H to the newest J!

My best regards at all and many thanks!
