8 pages, original, the photos were from the late 30s and you can actually see individual parts. These actual photographs from the 1930s have been copied by others but are very hard to see. This original is the most definitive we have seen for identifying parts needed and their function. This is a parts catalog, an ad, and a few directions , all in one. This was sent to distributors along with another booklet called \" Instructions: How To Operate Your Columbia \" [that I have listed ]which had help for jams--a real problem early on { and it continues today ! } It helps to match the picture of a each part with instructions which refer to parts by part number. There have been at least 3 attempts to copy these pages and the results are not encouraging . When a photostat is taken of a photograph the result is usually so bad you cannot see where the arrow goes. Several collectors have written to say they now can see in this original what the \" Instructions \" booklet was talking about. Others ordered several copies of each booklet at a deep discount to use as a sales tool when they sell a Columbia.

At the time of this revision, there is a Columbia mechanism on , 321384559156 that has the best pictures we have seen for . If you don\'t need the arrows pointing to each part and the name of each part, these pictures could be enough. There are 3 angles here that are better than the booklet. A couple collectors have added these angles to their \" Hail \" booklet.

Hard to imagine the genius of the person who seemed to start with only the idea and then came up with the way to make the coin magazine reverse and return any slugs just played to the player when he hit a winner !
