ajb, thanks, that IMCV "Mini Combicon IMCV/IMC" series is exactly what I'm looking for. And, it turns out my earlier measure when initially posting this was incorrect, the pitch I'm looking at is infact the more common 3.81mm (the IMC/IMCV's pitch) not 3.5mm, I'd initially measured just one pair of contacts by ruler when quoting, since then I've measured several together and by caliper. By findng the keyword for the IMC/IMCV series, "inverted header" by RS components naming, I also found that Wurth make something similar too, the WR-TBL 3093 series.
