I can check later when I get home or maybe someone here already knows... but there were some oddball numbers like this from a Canadien Amiga mail order house. After Commodore folded, they basically took A1200 motherboards and towerized them. Some models had accelerators, extra RAM, HD's, etc.
IMO, Commodore themselves would never have marketed an A1300. You ever notice how all their model numbers were divisible? A1000<>A500. A2000<>A1000. A3000<>A1500. A4000<>A2000. A1200<>A600, etc., etc. Guess that wouldn't apply to the A2500 though... DOH! lol
