During my research, I chanced upon this 1971 newspaper advertisement with cute drawings of industrial equipment, an uncommon sight at the time:
I did a cursory check - Tiang Wah Manufacturing is still around today. It does not have an office at Horne Road anymore, but it still has a factory at Jalan Woodbridge, now renamed Gerald Drive. The company has been around since 1967.
I hope it has been coping well during this pandemic.
