You continue to rock hard, Grant. Many thanks as always.
thx, indeed, looks to be same.Wow! Within measurement precision, the baseplate width of 25.10 mm with your newer Tech is the same as the 25.11 mm that I measured with my 1957 Tech. Gillette definitely changed the cap in later years, but did they keep the baseplate the same? By my eye, it looks like it might be the same.
