I’m in the process of rebuilding a Tasco 7TE, including stripping and powered coating mount parts, OTA, and replacing missing or damaged parts. The Bakelite body of the porro erecting prism is damaged beyond repair, so I’m reaching out to this forum. I have other Porro erectors but they are too big for the wooden case. Need the narrower one for the Tasco 7TE 910 mm. This has the 36.4 mm threaded end and the 0.965” receiver in the opposite end. This cylindrical body porro is ca. 49 mm diameter on the ends, it is smaller in diameter compared to the one from the 7TE-5 which is ca 58 mm diameter.
any leads appreciated! I plan to post the finished project in the appropriate forum.
