Older semiconductors Datasheets?

[Independence]

I came across a large box of unused assorted transistors in a box of junk
from a TV and video repair business that had closed down and left them all
at our rubbish tip trash and treasure exchange. Most are new although some
are rather superficially corroded on the metal cases.

I have searched at http://www.alldatasheet.com/ to identify the components
and have had some success, but many of them do not show an exact match.
Although I am a telecom engineer, and know a bit about them, I haven't had
much to do with such components for quite a while.
I want to make use of some in a couple of projects, but lacking the data
sheets I'm not sure what is what, although many are obviously power
transistors of some kind.

Is there a good source of data sheets for older components other than
http://www.alldatasheet.com/

Sometimes the above website comes up with similar numbered components but
they are obviously different components, just from the physical appearence.
Here are just a few I can't exactly match. Figures after the comma are
secondary numbers listed on the components under the main mumbers.

Sanyo C1050E, 5k
Sanyo B407 tv, 4g
Sanyo SD68C, 5A
Sanyo D416, 6B
SonKen 25D201
D621M, 8E
NEC 2SD388, R57
Sanyo 2SD68C, 4J
Sanyo C1050D, 5G
Sanyo C1050E, 5H
Sanyo C1050E, 5K
Sanyo C1050D, 5K
BU326A, T8947
NEC 2SD388, K3YA
Matsushita 2SD198

These are just som examples which may show the age of the components, there
are literally hundreds of others, transistors big and small.
Can anyone suggest where I might get datersheets on these "antique"
components please?

None of the numbers you've listed look particularly hard to find info on,

although JIS part numbers require more patience - add 2 before Axxx, Bxxx,
Cxxx and Dxxx parts from asian manufacturers markings. ie 2C1050E, 2B407
etc.

Unless you just like sorting and classifying junk, such searches may be
pointless, without an immediate practical application for the specific part
number.

If you do simply complete an accurate list of the numbers involved, make
sure a copy of that list stays with the collection, as it will save you or
somebody else the trouble, in the future.

I'd look for them with a 2S prefix added, and without the version or
binning suffix. For example, general information about the C1050E
part is probably available under 2SC1050 (it appears to be a 5 MHz fT,
600-volt part).
