Model 1 was made without evident technical changes, until it was replaced by model 5. There were some design changes (here are the lowest and highest known serial numbers for these changes):
* The first design (487 to 6058) reads on the front: “Royal Typewriter Company”, on the sides: ” –R– “, on the paper table: “Royal” or “Royal Standard”. No model number!
* The second design (8098 to 58786) front: “Royal Typewriter Company”, sides: “Royal”, paper table: “Royal Standard”. No model number! The name Standard was introduced to tell the customers, that it was equal to other machines that were “standard” at these times.
* The third design (59654 to 84030) front: “1 Royal Typewriter Company 1”, sides: “Royal”, paper table: “Royal Standard”. With model number! The model number 1 was added in the year 1911, when model 5 came out. Both models were produced parallel for some time.
The lowest serial number of model 5 is: 100172. Model 5 has always the model number 5 on the front frame right and left.
All versions of model 1 appear with either nickeled paper fingers, or normal rubber rolls on a rail. Maybe many of the older machines were updated with the newer system of rubber rolls on a rail. Model 5 always has this newer system.
Also, the early spools have four smaller holes around the flanges but the top and bottom flange on the early spools are the exactly the same. These early spools also have a small hole next to the main shift guide for the “drive peg” to fit into. The later spools have a bottom that is completely different from the top. It uses two small tabs to engage the spool as well as a “floating tab” to actuate the ribbon reverse mechanism. Fact is that most replacement spools, the smaller plain spools, will fit nicely onto the machine.
As for the keys. The tabulator lever was a regular option to add at purchase. You won’t find this key at every machine, but you can however find an empty slot above the right Shift key. Although not mentioned in the instruction manual, some of the Royal Standard 1’s also have a back spacer, which became standard on the Royal 5 (located on the left side). It’s been discussed whether the back spacer was a regular option or one to be demanded by the purchaser since not all machines have an empty slot for it.
Some people can’t easily locate the serial number. On some flatbeds it’s next to the bell (at the back). On others it’s on the carriage support rail rather that at the rear of the machine where it is usually found behind the carriage. Or under the left top panel, north of the spool. But, it can get even more confusing! Sometimes the back of the frame says one number and the left hand side of the frame (under the decorative plate that covers the typebars) says another. This doesn’t make sense, especially when the numbers are carefully typed on a single cast frame. Rumor goes, since the number at the back is lower than the hidden number, the hidden number might have been put on a casting that was approved to go from the foundry to assembly – it’s higher because the boss at assembly rejected castings, or they were ruined in machining, or they fell and got broken. Thus some of the series with the casting number never became part of a machine and never got a serial number. In these cases, the numbers on the rear are the actual serial numbers.
