My apologies Carl for inadvertently leading you astray. Clearly the Dreadnought is a very different lathe to the ordinary Portass versions which were I believe Myford clones.

Regards Brian.

Hello Carl,

For your question regarding the bull wheel. Yes it is 16DP, same as the change wheels.

Regards, Mick

Hi All, I have had a good look at the lathe and noticed more differences to all others I can find pictures of, it has a short rack and a different apron to others that and the headstock design plus the number 5 stamped on all parts leads me to believe this was a very early example so possibly quite a rare lathe definitely worth saving.
