Hi, back in November 1982 I bought a Durace equiped Shogun. I raced it for a few years and put it in the garage. I neglected it for 10 years, but in the last 10, it has seen the light of day a few times each year.
The bike is dark blue with all the correct brazeons including rear derailer. Single crown on the fork and concave at the top of the seat stays. Serial number is MOJ63461. I know it sat around in the shop a while before I bought it. I am looking at repainting it otherwise it is very good. It has the full Durace groupset including seat post, quill stem and hubs. Hubs are laced to 27 inch Araya rims. It was a 6 speed cassette type but I made it into a seven the same year I got it. ( thinner spacers and an extra cog )

I took all.....yes all the stickers off it the day I bought it. Its got a Tange Ritzy headset and I don't remember if it was Champion or Tange tubes. Seatpost measures around 26.5mm.

There are a few of these kicking around in New Zealand and also some Shogun 600s. The 600s are fully Shimano 600 equiped. Hope this helps your data base.
