2.4" Model 114 Unitron or the equatorial tube clamp rings with finder rings for the 8x30 larger finder.
Any one who has ever tried to use a model 114 or a model 128 with the dinky 6x23mm finder supplied by Unitron can appreciate the larger finder. Incidentally, the old model 105 with a 2" objective had an even smaller finder: 4x19mm.
These will need cosmetic refinishing. One has the set screws missing (standard thread and available from specialty shops) and the paint is compromised on one side of another. The felt inside the clamp ring is still usable.
Not many Unitron parts left around any more, so if you can find an 8x30mm finder around somewhere, you can fit it on your 2.4" with these. The finder cost $48 back in 1978...with brackets.
These clamps were $22 extra then.
