Hello, I have an old Toyota Forklift in almost perfect shape and I am trying to find the age(year)
I think the 1970s. Can you help me?

-Model No: 42-2FG20
-Serial No: 40-2FG20-60604
- Approx. Wt. 7260
-Type G
-Capacity 4000 LB
-Lifting Height 130 inches
-Other Numbers on the plate=57843-20541-71and B56.1-196?(can't make out the last digit)


Any help would be appreciated-I am going to restore this one

Also are there many parts available?

Thanks, Bob.
