When you see one you don't have, don't you get that "must have" craving? I never had the M40 Matchbox (now released by Revell) as a kid, but I do in my second childhood :)
Taking the antiquated M12 155mm mounting from a deprecated M3 chassis onto the latest Sherman M4 sprung version, it had a few pokes a Cologne but saw more action in Korea. Something nice to call in (if you can) on your radio net.
Yes, more painting to do, all backed up on the tray ;)
