Description
GFB Whistling Trumpet (suits all valves)The 5702 can be used in place of the standard trumpet on all GFB valves, and will make the whistling sound more readily than the 5701 (high boost and RPM is required to get the whistle from a 5701), and at a slightly higher pitch.? Like the 5701 however, it is necessary to run the valve so that all (or most) of the air vents through the trumpet ? Respons valves will typically not generate the velocity required to whistle when set to 50 50 venting.

Beware the shrinkage
Size: X-Large, Color: Chill
This shirt came looking as expected and the quality was good but it ran a bit small. I had to give it to my dad and it looks great on him!

NOT EVEN CLOSE ON SIZE!!
Size: XX-Large, Color: Light Blue
I'm not a small guy...im rather robust like a good Italian dressing..and this shirt is 100% disproportionately wrong! If your thinking 3xl sounds good for the price DONT BUY IT!! At best this is an XL t-shirt with a 3XL tag. I can't return it because I immediately cut tags off my shirts..I know weird right lol. Anyway hopefully you read this and like ex-relationships you 'MOVE-ON'!!!!!
