Very less is known about the history of Brahmam pens of Andhra Pradesh, India. Below is the little information i could gather from discussion with Mr. Ramanamurthy of Ratnamson pens and some info from Deccan stores.
Brahmam pens was started by Mr. Brahmam, the nephew of Mr. K.V Ratnam of the famous Ratnamson pens. The pen manufacturing was initially started in Rajahmundry and then moved to Bhimavaram near Vijayawada, Andhra Pradesh.
Few years into pen manufacturing, Mr. Brahmam passed away and the pen production continued under his son-in-law. About 6 years ago, he too passed away resulting in the shut down of the company.
The Brahmam pens are now very rare. Now and then few are seen in stores. Deccan pen stores have a few of them but they can be purchased only with a gold nib.
Some of the Brahmam pens i managed to purchase at reasonable prices. The green pens are purchased from Meenakshi stores in Bangalore and the burgundy ripple pen from Mr. Kandan of Ranga pen company.
