Nope. The best one can do is the fork steer tube. This fork tube has Akisu 85 stamped on it, which is in line with the owner telling me she won it in 1985. The serial number on the frame starts with WAK 56... M, which like all other WTC frame numbers, has no year reference.
Blows my theory that the horiz. drop outs frames were older than '80s. Of interest - The rims are stamped Worksman Cycles, Made in Taiwan. I have seen this before on the back rim of my Pizza Bike. I also have a set of 26" WTC rims stamped "Made in Japan", as is the 20" front rim on the Pizza Bike.
I speculate that Worksman switched from the Tange tube/BMX type fork like in the brochure above in post 428, and ran the "Crown" fork from the mid '80s
