My brother,
I have two Novarossi Mantra’s. Ones a factory Nova engine and ones a Hobby shop “deal” I got before I picked up a novarossi power supply.
The Factory mantra measures a tad different to what your stating above but is still close enough to a .23.
However the one from the hobby shop which is a “buy off the shelf version” measures exactly what your stating.
