I was going to order some Knobs but I didn't know which ones to order and thought it was better to wait. I will certainly give Bintel a call, it is only an extra 10 minutes on the way home...problem is I often pick up something else
As for the screws on the front, I thought they were the collimation screws but they looked a little small to do the job, I was expecting something a bit more substantial. If it is clear tonight, I might be able to give it another go...expecially if I can pick up some knobs.
