I am trying to identify the manufacturer of this diode so I can locate a datasheet.  Any suggestions or links to a site which has comprehensive logo identification cross references would be great.

Or maybe you know this manufacturer?

TIA.

Edit:  Okay I will answer my own question and say I found it, it is formerly General Semiconductor (now Vishay).

And I found a few interesting sites  which may be of interest to someone:

SMD Codes database
http://tkb-4u.com/codes-and-markings/smd-codes-markings/database

Visually identifying manufacturers logos.
http://howto.wikia.com/wiki/Howto_identify_integrated_circuit_(chip)_manufacturers_by_their_logos

Updates on 2017:

• The "SMD codes database is gone"  :(
• A database of SMD marking codes can be found here: http://www.markingcode.com.cn/ (worked nicely for me)
• Another nice list of manufacturers' logos can be found here: https://www.westfloridacomponents.com/manufacturer-logos.html

Good luck on your part code hunt! :)

for the SMD code I suggest this site, it helped me many times:
