The Inverto Deluxe 18R is the most complete staking tool set ever made by Kendrick and Davis.
It comprises an 18B frame with a No. 540S friction jeweling attachment, the standard stake and stump accessories, friction jeweling accessories, and other additional accessories. Early die plates had 26 holes. Later die plates have 28 holes. This change may coincide with the "S" prefix on the frame serial number. Standard accessories: 100 stakes "for modern watches", 20 stumps
The standard accessories are likely the same as those in the 18B, based on the information in the Inverto 18B & 18R brochure. These accessories changed over time. For each approximate time period identified, screen resolution images of the stake and stumps lists are shown at left and the full resolution pdfs are available for download at right. |
Standard Accessories - Earlier Sets
Early Stakes:
1,7,8,9,12,13,14,15,16,17,18,25,26,26B,26C,27,28, 31,32,33,34,35,36,37,38,38A,39, 40,41,42, 50,51,52,53,54,55,56,58,59,59A, 60,61,62,63,63A,64,65,66,67,68,69,70,71,71A,72,72A,73,73A, 80,81,82,83,84,85,86,(87)*,88,89,89A, 90,91,92,93,93A,94,95,96,97,98,99, 100,101,101A,102,102A,103,103A,106,108, 110,111,111A,115,116,117,118,119,119A,120 The Inverto 18B & 18R brochure lists the stakes in the earlier sets. The stake numbers are the same as the later list, but many of the hole sizes are slightly different for the same numbered stake between the two lists. *The Inverto 18B & 18R brochure indicates that the No. 87 is included in the older sets, but this is likely a typo. The corresponding No. 57 is not included and with the No. 87, the total stake count would be 101. |

Early Stumps:
1,3,33,37,60,69,78,79,87,88,89,90,92,93,94,95,96,97,99,99A See the Inverto 18B & 18R brochure, page 5, for a detailed table of the stumps included in the older sets. Note that the table on page 5 doesn't indicated that the No. 69 stump is included, but it is called out in the list on page 4. The inclusion of the No. 69 would bring the stump count to 20. It's unclear why there are two stumps marked No. 99 on chart on page 5 and both are indicated as included while the No. 69 is not. The inclusion of the No. 69 is confirmed by the chart of earlier stakes and stumps for the Inverto 18 and Inverto 600 shown on Tom Adelstein's helpful post on the subject. Based on a notation elsewhere on Tom's site, his chart may be from a 1950 Lindstrom catalog. |

Standard Accessories - Later Sets
Later stakes:
See the K&D Tools Catalog of 1961, pages 8-9, for a detailed description of the stakes for the modern 18B sets. The numbers are the same as for the earlier sets, but many of the hole sizes are slightly different. Later stumps: No definitive list of the stumps included in the Inverto 18B/R sets ca. 1961 is available. The full range of available stumps is listed in the K&D Tools Catalog of 1961, pages 10-11. |

Stakes ca. 1963-1972:
See K&D Staking Tool Punches & Stumps Booklet ca. 1963-1972, pages 2 & 3 for a detailed list of the stakes for 18B sets made during this period. The minor changes between this list, the list from the 1961 catalog and that from the ca. 1972-1993 tool catalog excerpt are described on the above page. Stumps ca. 1963-1972: No definitive list of the stumps included in the Inverto 18B/R sets ca. 1963-1972 is available. The full range of available stumps is listed in the K&D Staking Tool Punches & Stumps Booklet ca. 1963-1972. |

Standard Accessories - ca. 1972 - before 1983?
Stakes - ca. 1972-1983(?):
The stake list appears to be earlier than the 1983-1985 list below. The K&D Tools Catalog excerpt from which is was created uses the K&D company name as it was incorporated in 1972. See the catalog excerpt for a detailed description of the stakes. The list totals 109 stakes and includes the Incabloc roller stakes that appear on the 1983-1985 list as standard accessories but do not appear as such on the list in the 1961 catalog. They are a separate product in the 1961 catalog. Stumps - ca. 1972-1983(?): No definitive list of the stumps included in the Inverto 18R sets ca. 1972 is available. The full range of available stumps is listed in the K&D Tools Catalog excerpt, pages 14-15. |

Standard Accessories - ca. 1983
Stakes - ca. 1983:
This list was compiled from the Inverto 18R Build sheet of 1983-1985 described on the references page. Note the inclusion of the No. 130 Cone Miller in the 100 stake count on this list but omission of the No. 1 Set Punch. The latter is included as part of the frame assembly. |

Other Accessories
2 balance staff removers
No. 50 for regular sizes No. 50B for small sizes See the No. 50 Balance Staff remover brochure for more information. |
2 adjustable roller stumps
No. 305B (uses stake #8) for bracelet and baguette sizes No. 305C (uses stakes #9 and #10) for larger sizes The 1961 K&D tools catalog shows an updated design for these stumps compared to the "New Attachments For Staking Tools" brochure. The newer design looks simpler to make and to use. A larger, knurled stump eliminates the need for a wrench. The newer design also looks suspiciously like the Wilson Rex roller remover. |
