Do you need all the parts for the Carriage shown in your example? If it is only the Carriage casting itself that would reduce weight and shipping costs.
There were three versions of the Carriage, so it is important to get the correct one. The first was the one with the double wedge lock. That is the one shown in your picture. The second and third are interchangeable having the single wedge lock. The difference is the casting of the two with the third Carriage version weighing less. The picture below shows the three versions of the Carriage casting. All other parts, table post locks, the positioning stud & nut and the Table Riser Crank are the same. There were two versions of the Table Riser Crank with different handles. The Tabel Riser Crank you show is the later version and the most common. If you have all the other parts and the lock is the single wedge type finding the third version would be lighter to ship. Because the change to the third version was late in the Model 10ER production they do not come as often in online sales. I am providing you this information to help in deciding what you actually need and can use.
