I 've bought calculators from him, but never bought one modified. He sold recently one 19bII with the modified back door for the equivalent of 100 us dollars.

I have no affiliation with him in whatever way.

Here is a link for an advertisement.

Thanks for sharing this JL, however, when I follow this link, I don't see any clamshell machines at all; do I need to navigate somehow from that page, and if so, what do I click?

Just take a look at the last two pictures.
I know him, BTW. I might visit him one of these days as the battery door of 28S needs repair.

PS.: Just talked to him. Here is the link to his website:
