onecut... mine is not a csb, its a B

the csb (standing for model C school boxford) was a slightly shorter version of the C

its easy to tell the differences between boxford lathes

a. has thread cutting gearbox and power cross feed/carrage feed
b. has power cross feed/carrage feed
c. has neither of the above facilities
t. hasn't got a leadscrew / no thread cutting


then there is the aud, bud, cud, tud with UD standing for under drive (motor underneath lathe mounted in the cabinet)

check out the diagrams on the boxford spares website, it may help you reassemble

also search for the book, know your lathe: screw-cutting lathe manual (by boxford) there is a pdf available (free) so just google it. if you cant find it i might be able to email it to you
