I used the base model initially mined from Free3D:

Additions: I 'beefed' up the model for handling and ease of printing. Rebuilt the shield, added detail on the loading, redid the barrel, added handles on the trailer legs, a few other odds and ends. I think I got the scale close.

The Type 1 47 mm anti-tank gun (一式機動四十七粍速射砲 Isshiki Kidō yonjyūnana-miri sokushahō) was an anti-tank gun developed by the Imperial Japanese Army, and used in combat during World War II. The Type 1 number was designated for the year the gun was accepted, 2601 in the Japanese imperial year calendar, or 1941 in the Gregorian calendar.
The Type 1 47 mm AT gun was a relative modern design compared to other Japanese Second World war designs, being relatively light and easy to handle. As with many Japanese designs, it had a very low profile and was intended to be operated from a kneeling or prone position. The gun had a gun shield to protect the gunner. The carriage appears to have adopted a number of design features from the Soviet ZIK 45 mm anti-tank gun, a number of examples of which were captured by the Japanese during the Battle of Khalkhin Gol (Nomonhan) in 1939.
The Type 1 47 mm AT gun was introduced to combat service only in 1941, with the intent of it replacing the Type 94 37 mm (1.5 in) anti-tank gun. It was very effective for its role, with American personnel calling it "an excellent weapon, with mechanized carriage and a high muzzle-velocity" that "proved most effective in combat", though it was not always available in sufficient numbers. It had a high rate of fire and with AP shells was capable of perforating the front armor of the M4A6 (a slightly more heavily armored variant of the M4 medium tank[citation needed]) at 800 yards (730 m), though standard doctrine was to wait until tanks got closer if possible to ensure good shot placement. The weaker APHE shell, while incapable of penetrating the M4 Medium's 93 mm (3.7 in) of effective front armor, could still penetrate the tank's side (38–45 mm (1.5–1.8 in) of vertical armor), the most likely part of the tank to get hit, at a distance of more than a kilometer. It was issued to armored units as well as independent anti-tank units, and was fielded in a wide variety of areas, but most notably the Philippines and Okinawa, and continued to be used with diminishing effectiveness until the end of World War II.
