How many DP70s were made? That is a question which I have been trying to answer for many years. It appears that there is no final record of the exact number of machines. I will never find out. Out of curiosity and to get an idea of the range of numbers I started to list serial numbers, cinema, city and country of each known machine. The list of machines which been located by friends and myself since 1982. Although every effort has been done to keep the list up-to-date, you must be prepared to find out that some machines have been removed.

The machines have been located at one point since 1982 and may not be installed any longer. The list does not always reflect where the machines are today. Some projectors have been moved or scrapped since the date of recording.

During this process I've come across some cases of double inventory. Even Philips made mistakes. There are two copies of the oak wood box for the spares and at least two #2171 out there. It could misreading of the plates.

DP70 numbers: 0600 - 1499
DP70 numbers: 1500 - 1999
DP70 numbers: 2000 - 2729

How many DP70 were made?

 
It is unknown how many DP70 projectors Philips Cinema manufactured from 1955 until the end, around 1966. Philips Lighting has been very helpful, but alas, have been unable to find the records. I doubt records like that exist today.

The list of numbers starts off at #601 and ends with #2532 and then jumps to a final stop at #2729. There are no numbers above 999 and below 1300 (with one single exception: #1014).

Kinoton in Germany, the distributor of spare parts for the DP70, have estimated the number of machines to be around 1500 units.
 
 

A letter from Kinoton

 
28. August 2001

Dear Mr. Hauerslev

Unfortunately I cannot give you any information about the production figures of the DP 70. You would have to turn to Philips Eindhoven in the Netherlands. The only thing I can tell you is a number of 1500 DP 70 projectors which we sold in the period from 1955 until 1968. I hope this will help you a little bit.

Best regards, Renate Zoller

DP70 number plates

 
The DP70/Norelco AAII number plate

There is some confusion as to which number plate is the serial number plate of the DP70. Well, the DP70 MECHANISM number plate looks like this:
 
 
The American Optical Company (Norelco) upper base plate

This in not the DP70 serial number plate. This number plate is only seen on the DP70 base in the United States.

Plates like this have the following number ranges:

59-- _ _ _

1 _ _ _

and

6 _ _ _
