Is it a rare GMC-280 clear case prototype with a SBT-9 geiger tube installed???

NO!! I damaged my GMC-280 geiger counter's case and I need a replacement GMC-280 case from GQ Electronics. But it looks cool and it does work.

Look at that! I'd rather have a clear case any day cause it shows the good bits

How is this for a geiger case? I'm using Soviet SBT-11A square pancake alpha geiger tube too!

Really cool! Has anyone thought of an Altoids version? The pcb for the GMC-080 looks like it just might fit.

I have a GMC-280, I had to un-solder the GM tube clips and re-solder them. I also had to solder a jumper wire to the new clip location to make the SBT-9 work. That was all and it was easy to do.

I have never seen a GMC-300, so I am not sure.
