Description
R.S. Berkeley C Trumpet (Likely TPC621) – Lacquer Finish – .462 Bore – Monel Valves – Excellent
R.S. Berkeley C trumpet in excellent used condition. The closest documented model match is the R.S. Berkeley TPC621 C Trumpet, which R.S. Berkeley has described as an advanced-student C trumpet with a .462″ bore, 4.875″ bell, Monel valves, a one-piece handspun bell, double bracing, 1st and 3rd tuning-slide components, and a 3rd-slide locking screw mechanism.
This horn is best understood as a practical player’s C trumpet rather than a vintage collector trophy. Its value is in the feature set and usability: a C trumpet format, Monel valves, a documented mid-price/advanced-student design lane, and enough slide hardware to make sense for real C trumpet use.
Important distinction: this is R.S. Berkeley, not Berkeley Winds/BerkeleyWind. The two names are often confused in online searches, so I am being precise about the brand shown on the horn.
Important finish note: the current R.S. Berkeley TPC621 documentation I found specifies silver plate, while this horn appears to be lacquered / yellow brass in the supplied photos. For that reason, I am describing the finish as pictured rather than making a factory-finish claim. Please review the photos carefully.
The bell engraving shown in the photos includes the R.S. Berkeley marking and decorative engraving. I have not verified a special-production or special-bell lineage beyond what is visible in the photos. Any story beyond the visible engraving should be treated as unverified unless additional documentation is provided.
For the right buyer, this is a sensible way to add a C trumpet to the toolkit at a fraction of the cost of most professional orchestral C trumpets. I would position it for a serious advancing student, a player needing a second/backup C, a church or community-orchestra musician, or a doubler who wants a practical C without tying up several thousand dollars.
CONDITION
Excellent used condition overall. The horn presents very well in the supplied photos, with bright lacquered finish and clean overall lines. I see no major dents in the provided images.
There is light normal cosmetic wear from careful use, including small areas of finish wear, oxidation, or discoloration around some slide and water-key areas. This is typical used-instrument cosmetic wear and is shown as clearly as possible in the photos.
As with any used C trumpet, buyers should review the photos closely and ask any specific questions before purchase. If additional close-ups are needed, I am happy to provide them.
BEST FOR
· Serious student stepping into C trumpet repertoire.
· Church, school, community orchestra, or brass quintet use.
· Bb player who wants an affordable C trumpet for doubling.
· Player who wants value and utility rather than boutique-brand collectibility.
