Re: CAN YOU SHARE YOUR KNOWLEGE???
Your Wurlitzer branded horn is a Conn stencil. The "P" before the serial number was Conn's designation for stencil horns produced by them. "Stencils" are horns made by a manufacturer for another company, unbranded so that the purchasing company can put their own name or brand on them, thus "stenciled"
The "T" refers to a Bflat Tenor, and the "L" to low pitch. The Patent date is not the year of manufacture, rather it refers to the William S. Haynes drawn tone hole manufacturing patent.
Regular Conn catalog serial number dates to not apply to their stencil line of horns, and the separate catalog for these was destroyed in a factory fire, so determining the exact date of manufacture for your horn is a bit tricky.
Most Conn produced Wurlitzer horns were based on their Wonder Improved, or their New Wonder Series l models. If it is lacking a front high F, it is likely the former, and if it has it, it is likely the latter model.
