Mighty Boosh - Zooniverse jackets

[Lodril]

Being a big fan of the show, I'd love to put together a Zooniverse uniform from the Mighty Boosh. I think the jacket is the only tricky part. Any suggestions where I might find work jackets like these?

Wow, I figured finding these jackets would be easy... they're pretty simple, but I've looked and looked and seen nothing quite right. They are green (duck cloth, maybe?) and have the two breast pockets with snap closures, diagonal zippered pockets further down, and a zippered closure.

I've found jackets with each of those features, but never all together. Lots of uniform jackets and stuff, but so far no luck. If anyone has any suggestions on finding these, I'd really appreciate it.
