After searching high and low for a reasonable option to supply my battlegroup with 17pdrs, I found there aren’t many options in 20mm let alone plastic. I could order metal sets with corresponding crew from one of the reputable manufacturers for a pretty price, or I could salvage some PSC barrel extras from the soviet Zis2/3 set. I used the long barreled Zis2 which is 57mm (a little smaller gauged than the 17pdrs 76mm) and carved it down a bit to look more the part. I used various pieces to create the wheelbase and gun shield from my spare parts box. I used spare shurzen from armorfast for the shields and sprue for the arms. I also found some photo etched pieces to recreate some details to give them a little flair. To reproduce the small ball shaped muzzle break I sculpted some miliput at the tip of the barrel. I will sand/file to shape it more once it cures.
I have ordered a set of Waterloo British Paras with Pack howitzers for crew. It comes with 6 crew for each of the three guns. Below are shots from Plastic soldier review site:
