Doric pressure bar assembly part replacement

[pgfp]

I recently acquired a Doric lever filler. When I pulled the section to replace the old sac the little metal piece that the pressure bar slots into fell out in two pieces (corroded in half). The pressure bar itself cleaned up nicely so replacing that little piece is all that I need to get the pen filling and writing again. What are the chances of finding a replacement piece and where might I look? Are there any good alternatives for getting the pen filling effectively again?

Most vintage pen restorers ahem these pieces left over from parted out pens.  I would check with the normal parts and repair people you may know.  There are a few sizes of these anchors though and a special tool is needed (preferred) to insert the presser bar pre-engaged with the anchor into the barrel and onto the lever "ears" and the anchor must be inserted/seated with wings flared out to fir the barrel end and  with its slot at right angles to the lever in order to function correctly.

Thanks for the info! I'll ask around.
