Libelle 201 query

Hello gentlemen and others,
Im considering acquiring a Standard Libelle as a first private aircraft, after recently converting to a single Astir at my local club.
I have an opportunity to check one out, but have to travel a long way to see her, half way across the country.
One concern is whether the cockpit will fit my buddy. I'm small enough to fit easily. Can someone advise what the width is between the cockpit canopy rails? This would be the tightest part I guess, where shoulders would fit.
Cheers
Frank
