[AT] Case thresher elevator chain

[Mark Greer]

You are probably right on the 45 number. 43 does not seem to be a good
number for cast detachable chain. 45 cast detachable is 1.630" pitch,
1-1/4"wide, 11/16" sprocket face, 5.2#/10ft. 55 cast detachable is 1.631"
pitch, 1-19/64"wide, 11/16" sprocket face, 7.0# for 10'. I have an old
(1961) chain catalog for this type of chain showing many types of
attachments. Are the paddles bolted or riveted to the chain? If so what is
the bolt diameter and bolt spacing on a link? If I can ID it for sure then I
will scan the correct catalog page and email it to you. I may still be able
to source the chain and links but I'll have to do some digging.
