Takahashi 90-degree prism diagonal, part TFP0091. Made in Japan. This is the older 0.965-inch (24.5 mm) model, not the current 1.25-inch TFP0090 / TKA00547.
The dealer label on the original blue outer box reads TAK, 24.5I.965.1, TFP0091, old list $69.95. It is still in the white inner box with the Made in Japan sticker on the housing. Black prism body, silver nosepiece. Prism, not a mirror. Upright image, left-right reversed, same as other prism diagonals.
Fits 0.965-inch focusers and 0.965-inch eyepieces only. It will not drop into a modern 1.25-inch focuser without a 0.965-to-1.25 adapter.
Packed as shown and not taken out for use by me. Glass not inspected under a light. No returns, sold as described.
$50 plus shipping from Houston Texas.
