[StartQuote] I was looking through some old papers I had in my file and came across some things on the mufflers. Elco made parts in their Factory and had others made, shipped to the factory and assembled there. I found some PN numbers for a muffler vendor, PN A17695 and Elco had applied their P/N Div 6043, the starboard muffler asembly had a P/N A 17696. Elco Division 6043, 3 each, the muffler body port no. RA 90041, stb no. RA 90042 leads me to believe they bought only this part and were called underwater Exhaust Mufflers. I had notes on the butterfly Valve assembly used on mufflers. Again, they were partially bought outside P/N A20455. They were bronze and red brass cu-cupro #composition 70% cu 30% Nickel. The bronze C/U housing was a buy out from Van Blerck Co,, no VB210. Again Elco P/N 6043. The other section of the notes had in large letters: Van Blerck Co., Valves and Muffler Manuafacturer to be used on PT's 103- 145. This was an original Elco Inter-Office Memo from Irwin Chase, Managing Constructor at Elco........... [EndQuote]
