Looking for ARVN Insignias in Saint Louis, MO

Dear Sirs, I am Tan Nguyen, an ARVN. I served in Quang Tin and Quang Ngai, where you used to be, from 6/73 to 3/75 in ARVN Infantry Regiment 5 of the ARVN Infantry Division II in Chu Lai. I currently live in St Louis, Missouri. ARVN Infantry Regiment 5 was home based in Hawkhill LZ after you left. I have been desperately looking for the insignias of the units I served: 1. ARVN Infantry Regiment 5: a rectangular badge with a yellow fish-dragon on blue background with number 5 on it. 2. Recon Company of of ARVN Infantry Regiment 5: a rounded badge with a black/white eagle eagle on a orange color background. I would appreciate very much if you would provided me with any information about these insignias, actual badge or pictures, Tan
