Year of CCM Massey 304?

I'm helping a local museum document their bicycle collection. Can someone tell me the year the CCM Massey 304 Silver Ribbon was made? This bike is a mens'. The 1918 catalogue shows Massey mens' bikes with model number 356, and 358 with "B grade equipment." Did CCM change these model numbers with each year, and if so, does anyone know the match of models with years?

If an exact year is not possible, what is the year range? It has the pre-1917 head badge, and the serial number is 624534. This particular bike has the hygienic cushion frame. The rear hub is "Hercules Brake Patent Pending", the chain is 1 inch pitch, and it has wooden rims and wooden and leather grips. The front hub says "Phillips Celton Large Balls Made in England."

The 1918 catalogue also gives the following clues: "Models A, A1, 43, 44, 46, 53, 56, 64, 83, 84, 85, 86, 87, 302, 303, 304, 305, 312, 314, 316, 322, fitted with old Massey Crank Hanger.

Models 305, 306, 315, 333, 334, 335, 336 fiited with CCM Hanger.

Models 355, 356, 357, 358, fitted with "T" Hanger."

This seems to list every Massey model since CCM took over the Massey name.
