Are you looking for an S-38, rather than an SX-38?

If so, there are a number of versions, including the S-38, the S-38A, S-38B,
S-38C, S-38D and S-38E.

If you are not familiar with these radios, the S-38, A, B and C all have 2
half moon circular dials. The D and E are large slide rule dials.

There are many around and they are fairly inexpensive for old radios. Mke
sure you get one that is restored so that you do not have to service it. It
is easy and inexpensive for a competent hobbyist.

They are a classic radio, so enjoy it.
