I have a Demro WASP 9mm / .45 ACP. Does anyone have information on it or its worth? It fires from open bolt but it is a semi-auto gun.

+/- $160 new (way back when, of course).
Now? Almost anyone's guess depending on what condition, what furniture, does the lock work.....
$500 to a collector, maybe?

You may try asking David Spiwak (C3 Dealer).

If I recall correctly, he had one for sale not too long ago.

i don't know anything about your particular gun, but in case you don't already know this (i don't see anyone mentioning it) the BATFE has long since put the brakes on ANY open bolt semi's. so regardless of what the current value is, you do have something that will very likely never be offered again. that alone is worth something :)
