No need for pictures - your vertical bars set-up is a far better design than mine.
I doubt if either style is rare - just different. When I needed to replace my style of window pulls in the early 70s, I had no problem finding them at a junk yard.
I think you meant 8 bars, four of the bars with 4 pulls on yours?
Is there a diagram in the 47-55 Factory Assembly Manual? What page (Section; page)?
Thanks,
Tim
