Coming late to this, have everything now except parsing for 8a. I've _o-_u_h_r, which suggests this term for 'second pen', rather than _o-_r_t_r (as in paperback ...) which I thought of first - I just can't 'refine' any heraldic tincture term to get the needed letters. The letter 'h' for the 3d crosser is also causing diffs, as 3d would be h_h_m, which I thought was always hyphenated between 2nd & 3rd...? Staring too long, so if you had another hint I'd be most grateful.
