Jeff,
after few more pestering but necessary emails to the seller, he finally confirmed your initial doubt regarding the 'Yellow' booklet. This particular Ring Master is missing the essential yellow instruction booklet. So in term of it being the finest known to man, quality wise, may be maybe not, who can be certain. In term of completeness, well, this Ring Master is missing a rather important piece. So, with great reluctance, I abdicate the throne of owning the 'finest' Ring Master back to Mr. Nichols. The hunt for the prize continues.....
