I just ordered a Baltic in brass from Peak. The Baltic uses a TWOJ led and the same electronics as the Pacific. The head is smaller in size and they told me they are about the same size as a Matterhorn head, maybe slightly larger. You can also choose your drive level like the other models. I chose a high power which should be putting out about 110 candlepower. It uses a 17mm reflector (IMS?) which is cut down to 13mm and covered by a lens (plastic?). It has the same construction as the Pacific. The electronics screw in from behind. Should have a nice wide beam. The bodies that will be available are N cell, 2xN cell, AAA, and I think 2xAAA. I think all the bodies are currently available in HA and stainless. The brass just has the N cell available with the AAA bodies following in a couple of weeks.
You have to call Peak directly to order. They said the website will be updated in a few weeks. I am not even sure exactly what these things look like, but I know they will be keychain sized. I should get mine by the end of next week and I will post some pictures.
