Sheeesh, what a header! This is not a razor that pops up often otherwise it would have had a nickname like Fatboy or Brit's butthole or....
The Gillette New deluxe was the range that started around 1929 after the 'Old type' and 'New improved ranges' The range was made for around 16 years and the major upgrade was a slot in the cap and ridge in the guard that prevents any misalignment when inserting or changing a blade.
These razors are not plentiful and I can only assume this was on account of the great depression when wealth and spending was in short supply, add to the fact that Gillette sold millions of the 'Old Type' in the previous two decades and there are still many of them alive today, and the 'glitch in supply' seems logical.
It is a good looking razor for sure, teeth all present and straight, no cracks on the barrel, a pedigree of note with stamps covering the entire bottom section of the baseplate. The only thing that is not original is the colour of the cap, there is no plating on the cap and it reveals its brass base metal,
a Great find for us, who will be the lucky person to have this treasure in his collection?
