The strange Klingon E5 was a combination of leftover parts, including one engine from a D5, the boom of an F5, and the hull of an E4. (For various reasons, the shipyards that built those types could build more of those parts than the others. The E5 was a masterpiece of production efficiency, turning wasted effort into a handy little warship.)
The ships of the Starline 2500 series are cast in pewter, have supremely high detail, and are in a larger (1/3200) scale than the earlier, metal 2400 series of miniatures. The ships of either series will work with Star Fleet Battles, Federation Commander, A Call to Arms, or Starmada.
