TXBPF ready to tune

I haven’t posted here for a while, but  that doesn’t mean that all my New Year resolutions are broken! The TXBPF project has come along well, a pair of boards are now complete and need preliminary tuning. I had originally intended to use my miniVNA for this, but correspondence on the miniVNA yahoo group with M0YOM indicated that the tuning will be too coarse to make them work with acceptable insertion loss (thanks for the advice, James). We have an engineering dept here at work, and I spoke to one of the lab techs (jim) about getting some time on either a real VNA or a spectrum analyser with tracking generator. Whilst Jim was very helpful, it looks like the tasty bits of kit are in various Professorial research labs so out of my immediate reach. It looks like I need to trawl some local amateurs to see who has what that I can borrow. Any offers readers? In the meantime I will build my third board.
