Help please: Let's Play… NAME THAT RAM EXPANDER!!!

Hi, I've just bought my first Amiga 500 rev6a, and it came with a RAM expander, which I haven't been able to identify. I've looked through both the Big Book and Amiga Hardware Database, and haven't been able to find this board at all. It resembles a Zydec A500 512K in construction, battery type, and lack of labelling, but it's definitely not the same card.

Some good resolution photo's will be needed for anyone to grant help on this. Add them to this post so people can have a look what it is.
There was literary hundreds of A500 RAM expansions that were copies of known makes and a lot of them was not marked in any way, there may be no way to identify it.

It's just a bog-standard, run-of-the-mill 512 kB RAM expansion. Why do you need any further identification?

I like to know what hardware I'm using. also, that info could be used to update the the 2 hardware sites.

Yeah it's just a standard run of the mill clone, there was hundreds of them by the start of the nineties, and dozens of home made versions ever since. It could be made by anyone from anywhere, no way of knowing.

Looks identical to the one in my A500. I did remove the battery though before it started to leak. As said above it’s one of many expansions that were produced back in the day. I think I got mine from one of the many magazine ads back in the day. Something like Evesham micros or silica shop but it’s so long ago I can’t remember.

Actually I have a Power Computing ram utility disk in my collection which I'm pretty sure I got with this expansion ( as I did with my external drive with utility disk from here) so I think it is a Power Computing branded one (or at least one the sold).
