Elgin lathe collet closer – looking for part

I met a fellow who bought my turret and he sold me the main parts of a rare collet closer for my Elgin hardinge lathe

He was kind enough to make a drawing of one of the parts needed to make it close.   The drawing is for a similar part so it can’t be created from the drawing.

If you have the part I need, I’d love a scale sketch!

Thanks Tom
