In Production: no
In the early days of aluminum guitar production there were mainly two main players, Travis Bean and John Veleno. Gary Kramer worked with Travis Bean and was involved with marketing and design and greatly helped that company become a success.
Later on, Gary Kramer and Travis Bean had their differences, and Kramer thought it would be a good time to start his own company. He developed the V-Neck design and started production in the mid 1970s. After a successful run, he sold the patent to Henry Vaccaro of Vaccaro Guitar Co. and continues to evolve the neck and guitar.
Kramer continues to make guitars, but does not make aluminum neck guitars at this time.
Due to the production length and various models, this section is somewhat incomplete. If you have any information about specific models or have images that aren't in the database, please let me know!
I also want to send a special thank you to VintageKramer.com. This site is a literal gold mine of Kramer info with an extremely active user community!
