Hi
@ecologito
You've got yourself a Royal Model P portable - very nice machine from the 1920s!
Model Identification: Definitely a Royal Model P, produced from 1926 to around 1935. The telltale signs are all there: the distinctive boxy "flatbed" design (sometimes incorrectly called "flat-top" by novices), the classic Royal badge on the paper table, and what appears to be the signature duotone color scheme.
Dating the Beast: The Model P was produced from mid-1920s to mid-1930s, and based on the design elements visible, I'd peg yours circa 1927-1931. To nail down the exact year, you'd need to find the serial number (usually lurking on the back or under the carriage) and cross-reference it with the typewriter database.
Value? Don’t expect $3K. Quick scan of current market comps: a) Royal portables from the 1920s through 1940s are worth $500 to $800, b) Model P can typically be found for a few hundred dollars depending on condition — not as rare as we would think.

c) some recent eBay listings that I found actually sold show: A wood grain Model P with case sold for around $45, while working examples are listing between $120-$570.
Your typewriter: Without a test drive of the typebars, carriage action, and ribbon advance mechanism, I'd estimate your machine falls in the $150-$400 range - closer to $150-$250 if it needs significant servicing, or $300-400 if it's mechanically sound with just cosmetic TLC needed. (I am always interested in adding to my collection, send me a DM please).
Restoration vs. Flip Decision: The Model P is notorious for “paint flaking issues! Your duotone finish appears intact, which is a plus. These machines CAN BE worth restoring; depends on your stamina, so to speak, to deal with it all.
Don't you dare take this beauty to the dump!

Even in rough condition, these machines hold SOME value; I have a ballpark in my DM head. Every typewriter has some value, sometimes even for parts. This is a legitimate piece of typewriter history that helped establish Royal as the world's #1 typewriter company.
My advice? Either 1) sell her AS IS or 2) clean her up, get her serviced (investment $$), and enjoy the satisfying thwack of manual typing or sell to someone who'll appreciate this mechanical marvel!


Good luck.
