The 6 speed looks like a CL500M, and the smaller one a mini lathe.
There are posters on here who have and use CLM500s (A combined Lathe and Milling machine )
As said, it is important that the three jaw chuck has the second set of jaws (Note that like the set in the chuck, they will be, or should be, numbered, 1,2 and 3 ).
The mini lathe will be well known to many posters.
Neil Wyatt, having written a book on his Metalworker lathe, will, be very familar with it, and can give advice.
There should be sets of gears with both lathes. Don't mix them between the two machines.
Those for the mini lathe will be plastic, in all probability. The set should include:
20T (2 ), 30T, 35T, 40T (2 ) 45T, 50T 55T, 60T, 65T, 80T (2 )
The mini lathe has the Milling Attachment as an additional accessory, which does not normally come as a standard part for the lathe, but was bought additionally.
If you Google "Clarke CL 500M Manual", you should be able to download a manual, which will list the changegears available with the machine. Page 12 will show all the accessories that came with the machine, and allow you to identify the two sets of jaws for each of the 3 jaw chucks (See Page 25. Look at the teeth on the back. They will be the opposite way round for the internal jaws from those for the external. ).
