The subject frame is a Raleigh Competition 531 manufactured by an unknown Japanese source in 1982. We're unsure if the 2nd letter is a month (July) or fortnight (weeks 13-14) indicator. These could be 1982 models or early 1983 model year frames that were being stockpiled.

1982 was the year that Huffy signed their agreement with Ti-Raleigh to create Raleigh Cycle Company of America (aka Raleigh USA). Raleigh USA obviously wanted to create their own image as they made several changes including redesigning models, changing model names and new decal font. I believe that the timeline for the agreement and implementation of changes simply resulted in either Ti-Raleigh or Raleigh USA getting stuck with some stock that did not conform to the new corporate image.

As a result, an inventory of approximately 500 old style Competition 531 and International MKII frames had to be cleared. This was done though Michael's Cyclery of Ames, Iowa, starting in late 1982 and running though the end of January 1983 at a price of $269.00 US. However, it took longer than anticipated to clear these frames, with advertisements still running in Bicycling magazine in early 1984, with the price having been dropped to $199.00 US.
