On the “gramophone museum” website from Australia there is information about various garrard motors,

Could you please provide a link to this site and page?
I've never heard of it and have been unable to find it.

Online museum of mr. Chunny Bhamra, who is a member of this forum. Lots of interesting information, but unfortunately, there is some that needs an update!

Thanks.
I actually just found it and when I came back here you'd posted the link

Certainly the division in the 711 horn makes a benefit. And it its to reduce the size of the horn in the direction of the bend. This helps avoiding interferences in sound, i.e. helps the soundwaves running thru the bend with less interferences. Wilson recommended making the bends in the sound path in the narrower sections. This trick makes the horn narrower (dividing in two) at the bend. If you remove the separation, some frequencies are weaker, those with the wavelength similar in size to the narrow dimension. That division simply moves the weakened frequencies up into higher registers.

Hi Inigo,

Thank you for the explanation. I have downloaded The gramophone books by both p. wilson and g. wilson to read over my upcoming holiday.

My 112a has a number 50 motor, also single spring. I’ve been trying to glean correct information about this family of portables for some time, but it’s much more scarce online than that regarding the victor and HMV machines.

All pre-1931 UK Columbia portables had Garrard motors, but as Garrard's largest customer they often had the Columbia name stamped on them. As soon as their contract expired, the 201 and 202 were fitted with HMV motors.

One reason for the comparative lack of information is that when Columbia and HMV merged in 1931 to form EMI, the HMV archives were carefully preserved but Columbia's were not. HMV saw themselves as the senior partner, and a cynic might conclude that they deliberately suppressed the history of what had been their main competitor.

This guy is showing a garrard 5 (5a?) in his 109…. https://www.youtube.com/watch?v=L7BP6bfHt50

No, that's a Columbia No.8. Garrard never made soundboxes.
