You've got an unsuaul gun and parts are going to be a problem -- even simple parts like springs. Do you NEED springs, or are you just trying to be ready?
In either case, Magnum Research should be able to give you SOME help in the form of i
nformation about the type of springs used or, at least, the appropriate spring rates/weights required. You've just got to ask the right questions.
Most of the Magnum Research Baby Eagle guns are based on the Tanfoglio design (which is their version of the CZ design), and that's true regardless of where the specific model was made, or by whom.
The Wolff Springs site might help--look under EAA :

Semi-compact is an ill-defined term:
- if the term means
short slide/long grip you should probably use the
recoil springs for a Tanfoglio/EAA compact .40 (or .45 if you can find one) The typical .45 weight is 14 lbs. but a slightly lighter or heavier spring should work. (A recoil spring that's too long -- and stacks so that the slide won't open far enough -- can be clipped a coil at a time until it works-- you're venturing into unknown territory.)
Mag springs for any full-size Tanfoglio mag would probably work.
Extractor springs are probably the same for all Tanfoglio-based guns.
Hammer springs vary in the Tanfoglio lines, with newer ones being shorter (1.5" than the older models). You should investigate what's available from Wolff Springs -- I suspect your gun will use the older, longer spring, but that's a guess.
Put simply -- get the recoil spring that seem appropriate for the slide lenght, and the hammer and mag springs that seem to fit the gripo
If you need
other springs, you can try springs from other Tanfoglio guns such as a Witness -- EAA can sometimes help. In the worst-case scenairo, you may have to have a gunsmith make a spring; some gunsmiths can and will make springs -- others won't.
You can also periodically search the Numrich site
http://www.gunpartscorp.com/Manufacturers/M.htm for obscure parts. If you can find out what "semi-compact" means, you might find springs for 9mm or .40 versions that will work in your gun, if .45 parts aren't available. Almost everything for a Magnum Research "compact" is sold out today, but they get parts in all the time, and you can search or be notified when some things come in stock.
You might be best served by making sure it works and trying to sell it -- and find something that's going to be easier to repair and replace. Let someone else have your potential headaches. (A lot of folks will buy a gun like this and almost never shoot it -- in which case, it's a fine gun for them: they aren't likely to need replacement parts.)
