A pseudo TLR is a camera imitating the shape of a TLR, but with no coupling of the taking and viewing lens. The finder is not a true reflex finder with a ground glass indicating the focus, but an oversize brilliant finder. It is a camera with guess focusing.
The pseudo TLR vogue was around the 1950s and 1960s, when the Rolleiflex was representative of a pro camera.
Later, the pseudo SLR toy cameras used the same kind of trick, but were usually worse.
