There is little or no appreciable difference between a G-10, G-14/AS or a K-4 in 1945 production models. The same paneling and external parts are used. The tail wheel on K models were locked down and closed over, just like on a G-10. Even the oil fillers are in the same spot, because the ASB(M) engine uses the DB engine main block and heads, only difference is supercharger.
The differences are more noticeable around October 1944 when early G-10s combine G-6 surplus parts/tooling with as many K-4 components as was available. The G-10 was always the equivalent to the contemporary K-4, usually just a bit lighter because the K series has a lot more optional fittings installed at the factory.
