Yeah ive looked everywhere for the filter to no avail. Every image is either covered or chopped at the centre bar.
The more I look at the Museum example of the 67 models the more im certain its a white version of the screw on top Scott bonnar filter as the vent amount and position is the same as all mine.
I did however find an unusual filter on a 65 valiant advert that showed what appeared to look like a smaller version of the Victa Big black choke from the model 5S2. Something more resembling a round stubby marine style filter.
I was certain the sp62 was from 62 as mine is f62 and is from that year...I did notice one ad that said coming soon and it was nov 62 from memory so that makes sense.
