Novoflex lens adapter needed

[niels123]

Hi all,

I'm looking for a specific adapter: M42 for Castbal T/S. In the past I bought one, but I don't remember where I bought it and cannot find the invoice. I contacted Novoflex, but they don't know the adapter at all

Does anyone has information on how/where to obtain this adapter?

Here are some images. For comparison, I included the UNILEI (which has M39 thread).

Thanks!
Niels
