Help required to identify pantograph parts

[idlemarvel]

Often the least satisfactory part of Lego models of electric locos is the pantograph, because the real life items are thin and spindly.  

I found this model on a recent search which seems to have by far the best pantograph I have seem, by a builder called JM Barre, see pictures below:

I am having trouble identifying the parts used, though, can anybody suggest what they might be?  I am assuming they are Lego parts!

Here's another picture side on which may help:

Thanks for any suggestions.

EDIT: I think I may have partly answered my own question, I think the rods are part number 2880

download studio and look through the parts catalouge try searching for "bar" or "hinge"

Maybe also have a check searching for "https://www.bricklink.com/v2/search.page?q=Pantograph#T=A".

You're right, they're part of the range of 2&3 finger hinges that've been out of production for about 20 years. They're attached to part 2452 at the top and either the same or 4275 at the bottom.

Thanks all especially @CastleRail. That explains why the parts are hard to find. You need 16 of 2880 for 2 x scissor pantographs. I've managed to find 8 from 2 sellers on Bricklink but no-one (in UK) has more than 4. Ah well, all part of the joy of Lego modelling!

While it is not as thin as the old hinged bars, you can do a lot with 11090

and a bunch of plain bars

or you could also use a combination of lego battledroid arms in gray and 4L bars like this:
