Mr. Trevor, thanks for your input. I've noticed there are some things you seem to have left out to avoid weakening your argument such as:
1. There is a ladder on the civ3 DD located portside 33 cm away from the aft C-201 SSM allowing access to the officers quarters which is also on the Jianghu but is in a totally different place on the Spruance which proves the Jianghu & civ3 DD both have identical officer cabin positions and differ widely from the Spruance.
2. A fire extinguisher is fastened on the reverse side of a lifeboat support post showing only 8 mm of the handle from behind the post to your viewpoint of 1.436253 metres on a 37 degree angle running tangent from the communcations tower on both the Jianghu and the civ3 DD but is conspicuously missing from the Spruance which doesn't say much for either its backup fire control equipment or your theory Mr. Trevor.
3. If you zoom in on the civ3 DD you will see an automatic water pump, the ones powered by a Stewart & Stevenson Hi Shock generator set, located at 14 degrees on a cosine 68cm line based on a right angle from the 3rd window going along the starboard walkway and to the top left of the pump's stainless steel hydralic cover on a sunny day the reflection shows the corner of a box of tissue just inside the window sitting on a shelf. Sorry I can't be more detailed about the shelf but that's all of it I can see from the reflection on the pump from this angle. Anyways, that tissue box appears on both the civ3 DD and in the few available photos taken of Thailand owned Chao Phraya Jianghu frigate but the only tissue box on the Spruance I had a look at on the web was on the bridge used by the captain to wipe his runny nose.
Are you ready to stand down now Mr. Trevor or do you have something more substantial to support your theory with?
