In the "Wanted" section of the forum, Ivan asked about lenses for Hokushin 16mm projectors...

Because it is not possible to reply to a "Wanted" ad, I will do this here. Also because other people might be interested, as well.
A short history of the company can be found here...

There are two main types of Hokushin 16mm projectors that people usually come across. Note that in the US, these were sold under the Apollo brand for some time. Hokushin projectors were particularly popular in the Netherlands and some part of Europe, Australia, Japan and Asian countries.
Older style projectors
This is the famous circular loading SC-10 and the manual load projector SC-11 (i.e. the SC-10 without the circular arm). They use ELC (24V 250W) lamps. There are optical sound only models and optical and magnetic sound models.
The earlier produced SC-10 did not have an inching knob, the newer ones do. Some earlier ones might have also used an EJL (24V 200W) lamp or an incandescent one, but this needs to be confirmed.
There are several Xenon projectors based on this design, e.g. the X-350 and higher powered ones.
They were made in the 1970s and 1980s.
SC-10 and derivatives all use an unusual lens diameter: 44mm.
As far as I know, Hokushin only produced the standard 50mm lens and a zoom converter (0.8-1.2x) that screws onto this lens.
But there are sleeves around, which allow to use old-style, small-diameter B&H lenses. And these come in a large variety of focal lengths.
A new 3D printed scope lens holder is available from the Dutch company "van Eck"...

New style projectors
The slot loader SC-210 is one of the quietest 16mm projectors that I know. It also uses the ELC lamp and comes in optical and magnetic sound options.
There are several Xenon models based on this design, e.g. the X-310 (with 300W Xenon lamp), the X-360 (350W) and others.
Produced in the 1980s and 1990s.
These newer projectors used a standard diameter for their lenses: 42.5mm. This means that many lenses from other manufacturers also fit, e.g. EIKI, Bauer, Siemens, Fumeo, etc. And these are available in a lot of different focal length, incl. some zoom lenses.
There are provisions on the projector to screw in a scope lens holder, but I have never seen one. Only a drawing in a service manual.
But some scope lenses will screw directly onto the primary lens and can so easily be used in the Hokushin SC-210.
I would be happy to hear of others and their experience with Hokushin projectors. I quite like them, they are all sturdy and very well built.
