Comparison of frame channels:
The following figures show the difference between the original and new part for the frame channel. In figure 13 and 14 we can see a full view of the both frame channels, the difference being the added side part to the right of the frame channel in figure 13. A better view of this difference can be seen in figures 15 and 16.

Comparison of Staple holder:
The following figures show the difference between the original and new part for the staple holder. Figure 17 and 18 show the full front view of both parts, showing that the main shape of the staple holder has remained the same. However, figures 19 and 20 show how the inner part of the staple holder has changed. Figure 19 shows how the new part is made from one folded piece rather than two separate pieces being spot welded together. The main difference here is that the new staple holder now has a ‘roof’ over the place the staples would go and no ‘floor’ below them compared to the original part. This change does not affect how the staples are held in place. Figures 21 and 22 show the gap formed between the walls of the staple holder.

Comparison of the end bit of the pusher rod assembly:
The following figures show the difference between the original and new part for the end bit of the pusher rod assembly. In figures 23 and 24 we can we a top view of the end bit where we can clearly see how the original part was made of two pieces (in figure 24). In figures 25 and 26 we can see a bottom view of the end bit for both barts. Figure 25 clearly shows how the two original parts of the end were combined to make one part. This was done by cutting to folds on the roof of the end bit so that they could then be folded downwards so that it could be fitted with the rest of the assembly.
