See Article History Alternative Title: Raymond Fernand Loewy Raymond Loewy, in full Raymond Fernand Loewy, born November 5,ParisFrance—died July 14,MonacoFrench-born American industrial designer who, through his accomplishments in product design beginning in the s, helped to establish industrial design as a profession.
They didn't have anything new or ready for production for the model year. The major changes during the war involved the crystal filter design, the changeover to metal octal tubes, a new non-ventilated cabinet and the use of mostly JAN parts.
As with the late-WWII coil sets, the post-war coil sets used a single aluminum plate with silk-screened graphs. Many of the HRO receivers sold by National in the early post-WWII period will have several variations that seem to confirm that National was trying to "clear out" old stock. Several front panels have turned up with extra holes for the long data plate used on the HRO-W.
Expect to find many variations when examining HRO-5 receivers sold up to about mid The HRO-5A1 used 12 tubes - two additional tubes were necessary for the noise limiter circuit. Early versions of the HRO-5A1 may be found with the round S-meters, earlier surplus Raymond loewy panels which will have the National HRO-5A1 tag mounted just above the Noise Limiter control Raymond loewy many other minor variations that show that National was still trying to clear out old stock.
The last of the HRO-5A1 receivers will have a square S-meter, cadmium-plated chassis, a stepped-switch Crystal Filter Selectivity control and rubber insulated wire under the chassis in the wiring harness.
The late versions of the HRO-5A1 receivers seem to be consistent in construction and use of new parts and components. In late, an HRO-6 was produced in a very small production run that used the same numerical designation as the HRO-5A1 production run, It appears identical to the HRO-5A1 externally and the only difference between the two receivers is a slight Raymond loewy to the Noise Limiter circuit.
It's likely that the actual change in the Noise Limiter is that it was built directly onto the chassis instead of being built on a small chassis that was mounted on top of the receiver chassis. The HRO-7 was light gray smooth finish, the cabinet was modernized with rounded corners, the S-meter was mounted behind the panel and viewed through a cut-out and the knobs were restyled.
The matching speaker was also restyled to match the new HRO-7's appearance. Internally, a voltage regulator was added and the LO changed to a 6C4 miniature tube.
Coil sets were changed to not employ handles for removal and levers were utilized. Additionally, the graphs and charts were replaced with a linear calibration scale. Although the physical appearance of the HRO-7 changed dramatically, internally most of the updates to the HRO-7 were rather conservative.
NCDT or DR National's "Moving Coil" receivers utilized a cast-metal catacomb that carried the various front-end coils and placed them into contact with the tuning condenser by way of small contact pins and pin-receiving contacts. The catacomb was rack and pinion driven with a large knob on the front of the receiver.
The initial "Moving Coil" receiver was the NC Inthe NC was introduced and it featured both general coverage coils and amateur band spreading coils.
However, like most military receivers, the amateur band spread function was eliminated. These receivers were designated as the NCCS.
Immediately after the war ended, National did sell some NCCS receivers to the civilian market but most were considered "commercial" receivers. In a short time, National reinstalled the amateur band spread and designated the new receiver the NCD although some ads and manuals show the model as NCD.
The NCD added metal pedestal feet to the receiver cabinet. The single large knob that provided tuning when pushed in and changed bands when pulled out was unchanged from earlier versions of the NC series. Bythe round flange meter was replaced with a square flange S-meter, also from Marion Electric.
Note in the photo above, the NCD dial has all of the Band Spread scales near the center of the circular arc of the dial. Production of the NCD continued through most of The audio output is from push-pull 6V6 tubes but the audio circuitry utilizes a phase inverter rather than an interstage transformer National began using the phase inverter circuit with the NC in The matching speaker also with chrome bars and pedestal feet had the P-P audio output transformer mounted to the frame of the 10" Jensen speaker so, ideally, each NCD should have its matching speaker included in the sale nowadays.
The phone jack on the left of the front panel is for headset operation while the phone jack on the right is an audio input for phonograph or similar device. Since National had lots of "left-over parts" from the war production, the early versions of the NCD do have many small variations from receiver to receiver just like the HRO The chassis appears to have been punched for many variations so expect to find almost any NCD to have unused large holes in the chassis.
By the later versions, most of the parts are standardized and the receiver produced was consistently the same. National used "T" in the model number to indicate that the receiver was in a table cabinet while "R" was used for the rack mounted version.Raymond Loewy (/ ˈ l oʊ iː / LOH-ee, French pronunciation: [ʁɛmɔ̃ løui] November 5, – July 14, ) was a Franco–American industrial designer who achieved fame for the magnitude of his design efforts across a variety of industries.
He was recognized for this by Time magazine and featured on its cover on October 31, He spent most of his professional career in the United.

You are warmly familiar with the work. The first time you drank a bottle of Coca-Cola his bottle shape became ingrained in your memory.
From the prestigious design work he completed on the John F. Kennedy's Air Force One to the design of the familiar Greyhound bus, Raymond Loewy's efforts showed no limitations. Raymond Loewy has long been regarded as the most famous of American Industrial.
