Kerrison Predictor

[Neil Ashley]

Quite an old thread but I found this picture today of a UK based Bofors Gun still fitted for powered laying via a Predictor.

Presumably quite rare in this unmodified configeration.

If anyone is going to, or lives near(ish) to Woolwich, the Firepower Museum at the arsenal has a library.....pre arranged visits are required, contact Paul Evans (paule@firepower.org.uk), or phone 020 8312 7125.

I was researching detail of the 3" 20cwt AA gun used early WW2....in the box file was an IPL for a predictor......the 3" was also coupled to a predictor, some photographs show cables running into the base, and a set of photographs taken of the Egyptian Army show a gun with predictor.

I had a quick look through the IPL, I was more interested (from a modelling point of view) to get the dimension drawings, however there were only two photographs of the overall shape, but pages and pages of bits and pieces.

May be of help, not sure. The photocopying fees are very reasonable, and they always welcome a small donation. Very helpful people too.

Here is one photo of the Egyptian gun with predictor.

G'day all, does anyone have an image of the larger predictor described above?

I have a manual entitled:

Notes on Repairs to Fire Control Instruments - Part 1

Predictors, A.A, 3-in. No 1, Marks II to VII

1941

Second Edition


Is this the equipment you are referring to?

The book I saw was the illustrated parts list, it had each component broken down as sub asemblies. No dimensions though.
I was running out of time, they had kindly allowed me access on a day they were closed. Luckily there was some work going on, so I was allowed in.

I should have noted the details, but if you have anything that gives a drawing of the predictor, plus associated connections to the gun, it would be of use, if you're willing to share?

I cannot say if the predictor is the same as used by the Bofors.

The manual has a drawing of the predictor, plus a detailed description of the connections, plus CES.

Have PM'd you.
