I have the 1/24 p51D and a K in the stash.....but the k is sealed havn't opened it yet

Heres some info which may help
The only real difference between the D & K was the Aeroproducts propeller of the P-51K series built at Dallas,Texas
This propeller type (Aeroproducts A-542-A1, diameter 11 feet, (blades A20-156-24M) where introduced as an alternative type because at one time Hamilton Standard's output (supplier of the HS 24D50-87 cuffed blade type, diameter 11 feet 2 inches, blades 6523A-24) was in very short supply
Since the K-type propeller (hollow blades, rounded tip, uncuffed) led to vibrations and resulting oil leaks, this type was at one point discontinued, and the Dallas plant continued to build P-51's with the regular HS 24D50 unit. The designation of the Dallas produced K's was P-51K-xx-NT, the following D-models became P-51D-xx-NT's, while all Inglewood, CA, produced variants hat the -NA suffix.

The old myth with the 'Dallas' canopy is only due to different suppliers (sub-contractors to North American Aviation). Remember that the canopies were blown into shape and while setting up the Dallas production line, the shape of the canopy for the K's was slightly changed for additional sub-contractors, allowing a bit more headroom for the pilots. Early K's had the same (original) type installed as the D's coming off the line at Inglewood, California
Fact is that also at the Inglewood, line, at one stage a slightly different shaped canopy type was introduced, rather similar to the 'Dallas type'.

Moreover, the canopies were interchangeable.

In post-war years, it also happened very often, that due to the proplems with the Aeroproducts propellers, surviving K's (mainly Recon versions) were retro with Hamilton Standard units - this could easily be accomplished - in addition to the propeller only the reduction gear had to be exchanged, too. - And in a few cases, the exact opposite happened, i.e. a D-model was seen with the Aeroproducts propeller purly down to availibility

Late in the production run, and just post of WW2, a new type of the Hamilton Standard propeller was introduced, more precisely the blade, type:
the so-called 'paddle blade' - blade type 6547A-6, uncuffed with squared-off tips - the unit seen mostly on today's warbirds.
Surviving Dallas produced K-models also were re-equipped with this new HS unit.

external differences between D- and K-models are only visible on the propeller, but only during or shortly after WW2. As from the late 40's, only the serial number could tell where an aircraft had been produced, i.e. NT-suffix for Dallas and -NA suffix for Inglewood.

As far as i can tell theonky way of checking is by serial on the tail or on the data-block below the cockpit, there is no way of telling the external difference between a D- and a K-model

But i might be wrong in some detail i've missed
