From what I know and have gathered over the years this banjo, made in England by J E Dallas and Sons is +or- 100 years old.
Condition is very good and includes a solid hardshell case. The scale is 26-1/4+, the pot is 11", the tone ring is Whyte Lady, the wood is maple, the head is REMO, the 5th string is tunneled and the neck and bridge are radiused. There is a curious to me thin sheet brass stamped dish inside the resonator that presumably adds tone or volume or both. I don't know if that is original. The resonator attaches to the center brace with hardware that protrudes thru the center of the resonator. There is a spike at the 7th and I will include the radiused capo. I added the armrest.
There is discussion here on banjohangout about this style and brand of banjo. I had contact many years ago with Marshal Brickman (RIP) aka banjoiste here on banjohangout who also had a Jedson Whyte Lady. See the included pic of him with his. Keeping in mind the different look of his fingerboard relates to his stories of buying mother of pearl appliques at his local music shop and adding to his neck.
One of the sweetest features of this banjo is the top tension ring. The ring is smooth all around it's top. The brackets connect to the ring in a slot around the side of the ring. Besides the nice look there really isn't anything to snag on anything. A favorite feature (besides the sound to me). The banjo intonates well at the 12th fret though the action there is a tad high. If I was playing down there alot I might try a slightly shorter bridge. If you've never had a tunneled 5th, (I've had 3 including my Buckeye Custom #92) fyi that tunnel string tunes ok but not with the same ease as the other open 4. It takes a tad more coaxing than the other strings and may jump a bit above or below the mark. It just takes a little more finesse. Once in tune and no issues.
I'm thinning the herd. I have owned this for about 20 years. I have been playing this without the resonator and love the tone though it does boom sweet with picks and the resonator on.
