As I'm a huge fan of both the late Valentine versions and MILICAST's great castings, I've dropped them a mail and got this reply regarding 1/48th sale kits of late mark Valentine version (namely the A12 Valentine Mk.X/XI and A12 Valentine Mk.VIII/IX) from Thomas Welsh:
We have our hands full with 1/76...however I passed on your idea to our pattern maker who made the Valentines for us and has dabbled in 1/48 for his input.
Those 1/76th scale Valentines are little gems and a 1/48th scale version could be even a bit better. If you are interested, I suggest to drop Thomas a mail:
to show him how much interest there is. Possibly this could lead to some 1/48th scale kits:-) So we need plenty of mails. WRITE MAILS and use this chance! Need your support!
