Can I buy a baader 110mm erf filter?

Hello.
I have been visiting for a long time.
I plan to build an 8 inch h@ solar telescope soon.
Can I know where to buy the erf110mm filter in stock?
The baader also says it's out of stock.
It's so hard to find.
Have a nice day.

You could try the altair ones, but they say enquire about stock which suggests there is none...

Compared to the baader d-erf, do you think it's the same performance?
Thank you for answer.

I think they will be positively comparable.
