Battery door for the back door hp19bII

The HP19bII is a fantastic calculator with one of the most complete function sets. It was the workhorse of the MBA I did at the beginning of the nineties. Most of my companions were using this calculator.

However, several years later most units had been damaged at the same point: the side door. Nearly all units after a long time become brittle and break over time.

Hewlett-Packard recognized this problem and redesigned the calculator, moving the battery door to the back. There were other minor changes, with a darker brown body and black keys instead of the grey of the past version. This model is much more demanded nowadays - because it lasts.

I bought one in a local second hand site, but it was missing the back door. So I designed one for it. I thought that there would be exactly one unit produced ever - this was not a piece that breaks, and it was difficult to lose too. So color me surprised when a customer asked me where such back door could be found. "It is here", I said. 

So I take the opportunity to offer it to you all. However, I still think that there will not be a lot of orders - rationale is the same as it was when I designed it.
