I forgot to mention that the diameter of the springs remained identical between old versus new. Also, the coil diameter remained the same between both of the springs. This was measured using the Mitutoyo digital calipers.
It looks to me as if the length of the spring was changed only.
In the pix it looks like the no. of coils is just the same, it seems it is the base where the coil is attached that seems to be longer!? Could it be that old one could have just been used that why it is shorter? Just curious, your the authority on this.
From the detailed picture, it sure does look like the same number of coils as hiram pointed out. If diameters are tha same and material and condition is same, most likely length difference just due to set in the old spring.
I believe you are correct. The only difference I have noticed from old versus new is the spring length and the extractor spring might have a different bevel. I haven't decided on that one yet. On my old extractor pin, it looked as if it had three separate planes. Perhaps from use?
On the new extractor pin, it clearly has only 2 planes.
Anyone care to comment on this?
