Rangefinder.

10/10 .... just had to get my last one in. :D

Perhaps NFB can backtrack to my clue and the 15ft bit, and think of application.

Another clue : very famous in its day. ( 1940's )

Looking for a pic as the semi answer to my clue and I came across this.

Great bit of model engineering and what a challenge to photograph. Notice the 2 people for a sense of scale.

Don

Your in the right range!

John:)

It saves you having to guess!

They used to call them range finders and they were used to tell you the distance of the subject which you then set on the lens. They belonged to the days when most cameras did not have a built in range finder and no focusing screen. Looking through the hole two halves of the image were seen out of line. You turned the dial until the two halves lined up and then read the distance off the dial. Cost in those days about £3.50

That'll be about 3 days of what was my pay then John. Just to put it into perspective petrol was 5shillings and 3pence a gallon ...... about 26p a gallon in new money. :D Not exactly a cheap accessory.

Don

Just worked it out to about £70 in todays money. :eek:

Photography ..... an expensive hobby back then.

Don

Now too!

John

John,

Well done for the image you added. Shows the idea perfectly.
