I have taken notes of such M&A whenever I heard or found here and there. Example; Still took over Esslingen by 1968. Yale took Boge & Kasten, Solingen (known as BKS) 1927.
Your question, however, is the life span of the company. And sorry to say this, I have no record when such M&Aed companies started their forklift business.
I'm very much interested to learn as well.
