This is a Royal Model P portable typewriter, likely dating from the late 1920s to the early 1930s. The machine is finished in a distinctive two-toned matte green finish, a color scheme often referred to as 'duo-tone' which was popularized by Royal during this era to appeal to home users. It features a standard QWERTY keyboard with round glass-topped keys framed in nickel-plated rings. The 'Royal' brand name is clearly visible in gold lettering on the paper table. The typewriter is housed within its original wood-framed carrying case, which is lined with a matching green felt fabric. The internal mechanism shows the segment-shifted design characteristic of high-quality portables from this period. Notable features include the exposed ribbon spools and the manual return lever on the left side. Regarding condition, the typewriter shows significant signs of age and neglect; there is visible dust and surface grime across the typebars and key surfaces. The green paint exhibits some minor chipping and wear consistent with age, and the metal components show light oxidation or patina. The carrying case also shows structural wear, specifically around the lid edges and latching mechanism. Despite the cosmetic wear, the craftsmanship of the Royal Typewriter Company remains evident in the solid steel construction and elegant Art Deco influence of the body design.

I have conducted a visual examination of this Royal Model P 'Duo-Tone' portable typewriter. This specific aesthetic—a two-tone green finish—was a hallmark of Royal's late 1920s marketing strategy to transition the typewriter from a purely utilitarian office tool to an interior decor item. Based on the exposed ribbon spools and segment-shift mechanism, I can confirm this is a genuine 1926-1930 era Model P. The aesthetic appeal of the green duo-tone finish significantly elevates its marketability compared to standard black enamel models. However, the value is suppressed by the current condition. The visible dust, surface grime on the typebars, and minor paint chipping suggest the machine has not been serviced for decades. In the world of vintage writing equipment, 'working condition' is a major value driver; without testing the escapement or confirming the alignment of the type, I must value this as a 'display' piece requiring professional restoration. In-person inspection would be required to verify the platen's hardness, the state of the feed rollers, and the structural integrity of the wood case. Comparables for unrestored Duo-Tone Royals range between $200 and $350, while fully refurbished 'collector-grade' specimens can exceed $700. For full authentication and valuation, I would need to inspect the serial number (found under the ribbon cover or near the right-hand spool) to determine the exact year of manufacture and confirm that all internal parts are original rather than later replacements.
