Thanks for your replies. So if I understand correctly the 024 last is comparable to the capital last length wise and therefore longet than the 026 last?
The 026 last is definately shorter than any lasts I've come across in Grenson, Cheaney and Barker. There is even a clear distinction when I insert the same size 8 shoe tree in for instance the Loake Pimlico (capital) and Loake Kempton (026). The shoe tree looks crammed inside the Kempton.
