Motorola (Galvin Manufacturing at the time), I believe, manufactured more crystals during WWII, than anyone else.

Look for AF4K's website.

The current operator of AF4K is always looking for FT-243 style holders to stuff with modern & smaller crystal units & sell to hams.

I recently obtained a box of close to 800 or more FT 243 xtals ,haven't counted them all yet, and was going through them looking for any useful freqs on the ham bands and noticed how many different companies were making xtals during the war. So far I've identified at least 45 companies making these xtals.

 Is there any info out there that talks about how many companies were involved in making these xtals. 

Thanks
