Info on Taylor-Hobson 12 1/2" Lens

[Nazrat]

I inherited some lenses and have been weeding through them with my dad. A few have been easy to identify as they were mated to their large-format cameras. One that I'm working to identify right now is a very large lens.

It's a Taylor-Hobson "Television Projection Lens" No 258698 12 1/2" F/1.5 lens. It's weighs probably 60-80lbs and is approx 15" in diameter and about the same length. The history as I understand it is that it was used to project radar images from a monitor onto a projection screen some decades ago. It is mounted on an adjustable trolley with a hand-crank.

If anyone has any additional info I'd love to hear it.

Thanks,
Tad

I got a little bit excited in the first post, the diameter is approx 9" and the length approx 15"

That's still quite a handfull. 317mm f/1.5. Most impressive.

It is a handful. It was a good bit heavier than my 75-lb scale could handle. I'm new at this: although it says projection lens on it, would it be useful for a large-format camera? There were several that were in the same attic as this.

A very sturdy LF camera.

I got a little bit more info: It was used at one point with doublers and triplers to photograph Apollo coming out from behind the moon. "We got the magnification up to enough so the Apollo image was a little larger than a grain in the film, but the little chunk of the moon was awesome." I'm still looking for those photos.

Try this. Pentax spotmatic with flower-pot lens adapter. Possibly a single doubler/tripler. The mounting plate is still with it, but it weighs a lot and makes the package almost impossible for one person to move around. The tripod used is a horse too and is probably around here somewhere.

I've decided that I won't ever do anything with it, so yes it is:
