Hey guys found cheap GB style crank knobs.
Check out this site $2.00

Looks a little big.
Site doesn’t work. I would really like to see these!
They sold the one knob they had. So the page no longer exists.
Yeah it does look larger.. 4" from the outer edge of the knob to the other side.

It does look though like they have the proper trap knob though.

The page works, you just have to click back to Knobs (Aircraft & Radio) and all the knobs will load. It was on page 2. Between the “Large Raytheon w/ Handle” and the “Brown Knob”.
It was listed this morning, but its gone now.
Well I ordered it. It appears to be the correct number on the site.
I will let you guys know. Not too bad for $2 bucks.
Yeaaah… Like AJ said, they had exactly one of them, and they sold it. It was probably a 3S2B (matte black spinner knob) The 352B was probably a misread.
Bummer. 
Well I guess I lucked in and one got for $2.
I also ordered one. But it was on another part of the site. 
Trap knob?
Look at what I received in the mail today 
It is more of a mate black than gloss and appears to have the correct MS #
It has a weird divot in the middle of the top piece on the knob. Maybe a tool mark? Something easily filled and then painted.
Jackpot. 
That trap knob isn’t accurate.
Wow, nice find! And for just $2!
Wish there were more!
