Hey I’m in the exact same situation! I’m getting a C&P 8×12 as well and while I’ve used Vandercooks a lot am pretty new to C&Ps. I believe the counter that goes into the lock up is not meant to be printed onto your paper. I think you’re supposed to set them outside of the printing area. Didn’t even know these counters existed until I visited my press. The printer who’s selling it to me has a lot of accumulated materials he’s giving to me that I may not actually need but he wants to give to me because he won’t need them either.
For instance I’ll have a few extra lock ups I can sell and some extra lead strips (if you’re interested in doing lead type).
I don’t remember if there were any extra large counters. I think there may be one, if any. If I can get your email too I can send you the same set of photos I send Samantha and you can make a choice from there. I’d say the chance of finding one that fits your press from this set is pretty good though, being that we have the same model and size.
