G'day folks,
I'd say CyberJack has the right model here. Looking at the fleaBay pics, the front opening is offset, typical of the Model 14 and 19 [looks like those used a very similar basic shell].
The Model 14 catcher was used on Victa Corvette and Cortina series in the 1964-69 period, and a couple of uncommon models [the Self-Propelled 2 160cc Model 568, and Key-Lectric Model 564] in 1968-9.
The Model 15 for Mayfair models had a wider, symmetrical opening - pics
HERE. It was used on both Mayfair and Storebrand mid-arch models from 1968 to 1980.
