Another aspect of your modification is that the last cog should stay the proper way still because the cog has twist tooth design to aid shifting. By putting it backward, may be hard to shift onto and off it. Do you have enough threads covered by the last spacer? If yes, remove the spacer and flip the last cog as intended, resting on the built-in spacer, not to mess the already poor shifting between very similar size cogs.
And about product code, maybe it's 6208body with a swapped freehub from a 6speed. Clearly your freehub is fit for 6speed only (or as many as you like with the right spacers and friction shifters using ultra narrow 10sp chain with ultrathin 10sp cogs and spacers.. fit as much as you can.
