How many 1 letter domains are there!

[DotUSDomains]

hello all ,

Is it possible to find out how many 1 letter domains are available

I dont mean ones that have been reserved like 1 letter dotcoms.

All 1 letters in any extension that were/are available to register.

Thanks (just after numbers not ext codes etc..)

there are loads of 1 letter domains left.

BUT they can very often be pricey.
