翻译:根据我的知识,同一尺寸的美国表除了表壳外,不同表厂的作品之间可互换的零件其实很少.
而且我不知道有专门写有关美国表互换零件的书籍.
如果不同表厂之间的同尺寸产品有可能互换的话,要么就是表厂之间合作的成果,譬如当年华生和新老交接期的侯活合作生产的桥式机心.
另外一些较为易见的例子就是,纳沙表业公司(1859-1862)与华生同时期的作品, 少数被侯活买下的汉密顿机心, 还有汉密顿治下的伊利诺斯产品. 因此,汉密顿400号和部分伊利尼( Illini)的零件是可互换的。
还有些私标的产品非常容易令人混淆,譬如波尔,伯灵顿和华盛顿公司的产品.
令人惊讶的是,工业化的瑞士钟表产品的零件可互换性倒是非常理想. 这是因为瑞士的制表工业有着很多专门制作特殊部件的专门作坊, 其中就包括了擒纵,摆轮,游丝,轮系,指针和面盘等零件的作坊。
有一本叫做"Bestfit Encyclopedia"的书籍记载了大量有关可互换件的信息,而且很多都是关于同一种零件适用于那些厂家的特定型号产品.
自从埃尔金和波尔都试过从瑞士进口零件和机心成品,我推荐的这本书应该可以帮到你.
原文:
To my knowledge there is little interchageability between watches by
different American makers beyond cases.
I do not know of any book on this.
the closes possible exception are watche made by one company for another
such as the Waltham watches made for Howard during the last days of the
old Howard company and the new Keystone Howard operations.
The only other examples I know of iare similar, The Nashua watches
relabeled Waltham, A token number of Hamilton watches they labeled as
Howard after they bought out the Keystone operation, and some Illinois
labeled watches made by Hamiton after they took over that company. This
parts for a Hamilton 400 are interchangeable with corresponding Illini
models.
There is potential confusion with large private labels such as Ball and
operations such as the Burlington Watch Company and the Washington Watch
company.
Surprisingly Swiss watches have a lot more parts interchageability. This
is because they industry had specialists for part escapement assemblies,
called Assortisments, gears, pinions,balances, balance springs, hands,
and dials.
I have not seen catalogs of these firms but there are books like the
"Bestfit Encyclopedia" which identify parts by make model and part
number and identify which are used in more than one model.
Since Elgin and Ball brought in some Swiss made movements there are some
exampls there so I guess in a round about way the book you want s the
BestFit Encyclopedia, which is pretty easy to find. Bestfit was a maker
of parts which they sold to jobbers to resell individually or as kits to
for independents who wanted to have part on hand.
