Hi Jaap,

Save your cash and just get a roll of "Geotape or Letraline" and stick
it on your existing screen (make your own 24x54mm guides).  Better still
take an art-knife and cut a couple of guide lines (as it's plastic and
scratches real easy) into the surface of an old or second hand
focusing-screen.  You can even just make a drop in cardboard
*slide-mount type mask* that just sits on the focusing screen, a cheap
solution to the problem!

Just get the dimmensions for the lines from a local dealers stock or
Tamron direct, or just measure the 24x54mm back if you allready have it
and transfer the dimmensions to your screen.

As for the above suggestions I have not done them on an ETRSi, but have
with an RB67, same principle.....it works great!  And as we ETRSi people
know, what you see through the prism *is not* what you get on film, so I
would not beat myself up over +/- a milimeter here and there (just look
through that prism & grip it with your hand and twist - not the best of
designs......but we love it anyways).

And no, I have not found a suitable reason (excuse yet) to buy a 24x54mm
back yet.  Don't forget you'll need a good *anti-newton* glass enlarger
carrier for the film, a better buy than the screen IMHO!

Cheers,
Chris
