    Very interesting site.......my question is, when and why were wooden movements given numerical designators.e.g. 1.234.6? Was this done originally by the manufacturers or are these numerical designations a product of a contemporary need to catalog?
    What parts of the movement are key to the numerical id and are variances on the movement noted as part of the total number designation?
    Thanks,
    Bruce

    The numbering is a modern convention designed to identify and classify variations of different wood movements and, to the extent possible, attribute them to various makers. Snowden taylor has done a great deal of work to establish these clasifications. This website has a bit of information; I am not sure how up to date it now is. The website mentions NAWCC Bulletin # 208. That issue came in two parts, of which Part I is devoted to Snowden Taylor's work.

    I'm hoping someone will bring me and others up to date if I am off-base here.

    Bruce,

    The October 1980 NAWCC Bulletin contains a lengthy article by Snowden Taylor identifying Terry-type wood movements by makers and users. The article has been updated several times since. The classifications are Dr. Taylor's.

    The numerical designations are from Snowden Taylor's authoritative movement identification charts, first published in the October 1980 Bulletin, Number 208, Part 1. This is of course available at the NAWCC website, for members. In addition, it has been posted online, with Dr. Taylor's permission, and we have a link to it on the Cog Counter's website (which is a work in progress)

    http://cogcounters.org/

    Look for a link entitled "Clocks are us- Wood movement ID"

    Wood shelf clock movements are catalogued according to certain features, such as the shape of the verge button, the shape of the tip of the escape wheel bridge (most are squared off, Seth Thomas and a few others rounded them), the presence of rings around certain pivot holes, etc. It is very easy to use, and is a great tool for determining whether a clock you are considering buying contains the correct movement.

    Amazing these three replies in a short period of time with consistent information. This link, accessible alas only to NAWCC members, leads to the Table of Contents of number 208, Part I (I hope).

    Looks like we were all helpfully typing away at the same time.

    As usual from this message board GREAT information.
    I know of the id of Terry movements but were there other studies done on other makers,e.g., Kirke,Jerome, et al, or was this study exclusively for Terry movemants.
    I know some made their own movements,copied Terry, and/or also bought from him.
    Thanks again,
    Bruce

    The idenification is for Terry-type movements, which were made by many different makers. Other styles, like "groaners" are not included.

    Thanks RM,I was orienting my query regarding wooden movements made by other makers.
    I have a movement that has no id and one purportedly made by Charles Kirke.

    Yes, most known makers are covered, not just Terry and family. Towards the back of the Bulletin there is even a section covering movements from the Leavenworth and Hopkins & Alfred shops, even though they are not really "Terry-like".

    Bruce, if you post a few pictures of the movement, perhaps it can be identified.
