The screws are certainly not Meccano.
These were usually brass slotted screws,
I think they were 5/32 or maybe 3/16.
The set I had had hexagonal brass screws.
The original Meccano strips were green while the plates were usually red.
Then I had TEMSI which was a German variant of the English Meccano, which fitted with the Meccano parts OK, although the finish wasn't as good especially on the shafts which were perhaps a few thou thicker and some gearwheels didn't fit on them.
The colours of the latter were different too.
The 8 way power botch has no ground at all, the lead feeding it is only 2 core.
