I can't be 100% certain but I think this a 1/35 Patlabor AV-98 Ingram 1 by B-Club Resin Kits. There is too little information on such out of production resin kit in the past when mecha kits were still in their infant stage as some of these kits are over 20 years old. A lot of these kits never get to be built to finished product such as this. Patience paid off and slowly but surely, I managed to obtain some of these rare Patlabor resin kits from overseas.
1/35 scale Patlabor remains a favourite size that I would go for because they stand approximately close to Master Grade (MG) 1/100 scale Gundam model kit. I like such size despite their lack of articulation and zero gimmick. This kit feels genuinely good on my hands for its hefty weight. Good quality resin that is heavy and solid as expected from Japan goods in the past.
The previous owner certainly did justice to this kit by building and painting it skill-fully. The 2 antennas on the collar are made of metal. The Ingram 1 takes on a dramatic pose like as though it has just taken out the nightstick from the shield, extended it and on ready stance to strike criminal Labor.
