I recall that there are two manufacturers of blue LEDs: Siemens and
maybe Hitachi. The Siemens' is named LB 5410-H0, it emits blue light at
480 nm and gives 2.5 mcd (milli-candela) at 20 mA. It's 5mm in diameter and the
order number is Q68000-A5700.
BUT: You won't like to order them. The last time I saw a pricelist they were
well above $10 (or even $100 ?), so the LEDs will be more expensive than the 
remaining parts.

Greetings, Frank.
