Rubies Han Solo Blaster - take apart?

Hi All

I've managed to acquire a broken Rubies han solo blaster.

The sound is not working, and some of the plastic is cracked or broken - easily repairable though.

Anyway, I tried to take apart the blaster last night to check our the wiring, and couldn't seem to get the * thing apart.

I know from modding a hasbro E11 that some areas were hard glued in, and could only be taken apart by cutting - something I was hoping not to have to do with this blaster.

Has anyone here managed to take one of these apart completely? If so, any chance of some pointers?

Many Thanks
