The Romulans were my favorite race in Star Trek and in Star Fleet Battle for many years. I've separated the fleet into three groups. The early Romulan "bird of prey" or War Eagle era in SFB, including the various early sub-light designs converted over to warp, once the technology became available. The Klingon era of ships sold or transferred to Romulan service. And the new generation of Romulan vessels lead by the Sparrowhawk light cruiser and Skyhawk destroyer.
My earliest models are the first version of the War Eagle, the Romulan ship depicted in the original Star Trek series. These models mostly date to 1981-82. And the Condor dreadnaught, which dates to 1983, I think. More recently I've added various "Hawk" light cruisers, which are actually slightly larger than the War Eagle which became the "standard" cruiser of the Romulan fleet.
Here are some pic of the older Romulan vessels for SFB

And the newer Romulan Hawks:
The current Amarillo Design Bureau miniature for the War Eagle is much larger than the original, which conforms to the animated and original series size. The Romulan Snipe miniature (frigate class) is roughly the size of the old War Eagle, so I'm going to sculpt a smaller Snipe and cast it to add to my fleet before the Romulans become active in my SFB general war.
