Thank you Darren for uploading your video as it has been a handy reference to see the internal workings of our old Philips EL3546 A/78 that needs repair and belonged to my father. It's missing both Idler Tyres from the FF & Rewind Hub and the drive belt had also stretched. Pity you didn't give a length or part number for your belt as that would have been handy. I have used the string method around the pulleys for this machine and came to an estimated total length of 500mm. From there, I decided to order a Square Profile belt at 46cm (18.1") long x 2.4mm that suits the Philips EL3547A as a belt for the Cossor CR1603 seemed far too short at 42cm (16.6"). From what I've read, the Philips EL3546 A/78 is the same machine as your Cossor CR1603A and the Stella ST456, but not sure about the Cossor CR1603. All I have read indicates these are built in 1963 and possible the first conversion from valve to electronic. Estimate trye sizes for the idler hub are 32 mm ID x 42 mm (max) OD x 4 mm thick wall for the large tyre and 26 mm ID x 36 mm (max) OD x 4 mm thick wall for the small tyre. Getting quote to reproduce tyres with extras to be listed on eBay. To be confirmed. Hope this helps you and others. Regards. Daryl

Thanks for all the extra details, Daryl. Ive noted to film belts in the future if i make more videos.
Nice find. Looks in good condition.
The outside is good I agree, Pity about the pot metal problems though.
