English Threading

Razesa-Frames-Zeus-1985-Catalogue

According to this scan (cadged here – http://equusbicycle.com/bike/zeus/zeus85/index.html) my own 1985 Razesa bike has probably got English threading at the bottom bracket.  This is good news.  I will order the Shimano 600 crankset for square taper bottom bracket and be able to install those axe-head MKS Lambda pedals.  The image below a legible cutout of the bottom of the page that appears above.
