James ThormanWinding Stem Interchangeability With Bunn Wadsworth
The stem and crown are case parts. Hamilton bought Illinois and eventually Illinois took off company from Illiniois Watch Company. The case style used bythe 992 series and maybe some others Are perhaps the same cases Illinios put their movements in.
In fact purchased a Bar Over Crown Bunn Special 16s and the Crown is signed Hamilton.
I ordered a 992B stem and from the measurements not so much the exact profile are near to the same. I expect it will work. Would someone have experienced this?
Looking for this stem is more fruitfull in finding listing for Hamilton than Illinois, in particular Bunn Special. ThankYou.
Regards, James

James ThormanHello.
There are three numbers found on the case. It is NOT Signed Bunn Special. The crown is signed Hamilton Railroad.
Case Back ends in 5576,
Bezel shows E5576
Frame is (close) E5524
Movement is 5276302
I resized the 7 pics and I can post 7 pics if I did them one at a time.
Hamilton 992B while I don’t have one is one of their Grades I guess. I saw an ebay listing and the stem looked right and had the right dimensions.

James ThormanI tried the fit with a 992B Case stem. The seller did not know the case maker, the stem was in a drawer marked 992B.
A total fail, the threads do not match. The stem at the widest spot passes straight through the bushed hole in the Fahys 181 Bunn Special Case.
Back to square one!

Kevin HoffmanIt might be time to see a watchmaker and have one made , or he might have one in stock , if you have the tools it is just a matter of turning and tapping and a little filing

James ThormanI modified the title a while back OR had a similar post in another section. Just a note here to say that two very nice IHC members helped with my issue.
Paul Davis offered to make me one from the remmnents AT the same time , Gary Cochran recognized he had a very likely spare and sent it to me. (Thanks again).
I used a stem reaming set out of the vintage and excellent area of support for us All, the folks who sold worthy tools and parts that we now are helped flurishing a freat hobby.
The threads were ALMOST correct. Out of two perameters pitch and threads per inch, my sense, I was not ABLE TO thread it to my original crown. BUT a couple of runs putting the crown through some careful reaming I got Gary’s stem to go with this Crown, perfectly.
