Jack,

The Cassen & Plath web sight shows many options that the C. Plath may not have offered.

1. 2 styles of whole horizon mirrors.
2. Adjustable Sun filters.
3. Quick adjust for index error on the micrometer drum.
4. White frame option.

Both are very well made. One thing I don't like on both makes are the plastic micrometer drum release triggers which can be easily broken.

Cassens & Plath versus C. Plath sextants
From: Jackson McDonald

What are the relative merits of Cassens & Plath versus C. Plath sextants?

I was under the impression that Cassens & Plath was considered a somewhat better instrument, if the sextants are otherwise in comparable physical condition. Now I am wondering, however, whether my impression is based on fact or bias or personal preference.

Any thoughts from the group?
