Patent dates?

1. I think in the later half of 1923 because I have seen 1923 models with single glass panes.
2. English/French keyboards are very common in eastern Canada, and I wouldn't describe them as scarce, but not dime a dozen either. Like all keyboards/typesets that were meant for certain markets, they will be more commonly found on machines within that market.
3. Apparently rebuilt Royal models have serial numbers with a Y- prefix, and since the rebuilding of machines such as yours probably wasn't done until the machine had served a fair number of years, I would guess that most would probably date from the early '20s onward. 

Could you post a close-up photo of that sticker?

If you are talking about that gold sticker to the left of the "Royal" branding on the back, that is a Canadian patent number listing, and refers to some of the components used as part of the typewriter design. In fact, you can search the Canadian Intellectual Property Office website using those patent numbers and get a more detailed description of the componenets to which they refer (such as the inventor/designer, the company associated with the patent, date of filing, etc.).
 

OK, maybe fly in the oinment as I use this machine more.

1.) press 'tab' key and it really slides carriage over hard.  "Thwack!"

2.) Now the keys are locked!  (They go up about 2/3rds of the way.)

3.) I can press the silver button on left-side of carriage & release the keys so not really a problem.

Will continuing to do this eventually damage the machine, or just something old ones do?

Everything else works fine.  Just don't want to damage something 92 years old.

Thanks in advance for comments / suggestions.

3. Sounds like margin key block? is getting stuck. When the carriage hits the end of a line (margin) it locks the keys on most machines.

Sorry if long or makes little sense.  Need typewriter glossary or somthing.

Margins seem OK.  Six spaces after bell.  Two spaces after Margin Release, or if hold it down will type off page.  Return & types as should.

Only happens when using tab key.  I'm a novice, but carriage moves right with far too much force than I'd think neccessary.  Tension adjustment?

1.) Press Tab to indent paragraph, center on paper, etc.

2.) Keys sometimes 'lock' or it will type but carriage doesn't advance.  

3.) Press round chrome button on left side of carriage (in center of knob you turn to feed or advance paper.)
Audible click as "something happens" and type away!

Like I say, not a major issue, but don't want to mess it up if some sort of buffer or cusion is hard, worn down or missing.

Carriage tension adjustment screw only controls it going from right to left correct?  Increasing likely solve not advancing after keystroke, but would also make carriage slam into those tab stops even harder? 

Clearly have a lot to learn about tweaking old typewriters!

My typewrites make a loud sound to on tab. Its normal. You have to adjust the tab blocks to let it stop where you want it too.
