What screw is this on the SidKit Blaster?
I've lost it and need another one, but I'm not sure what to look for!
Any help would be much appreciated!

Best,
Brenton

It is not an accurate screw to begin with so I would just use the Worldcon photos for reference and find something close that fits. No need to match Sid's screw because it is right anyway. I will look and see if I have any pics of the real bulldog screw. I may even have some extras.
