The Avro Shackleton Maritime Patrol aircraft is fairly well known and there have been recent kits of the MR2, AEW2 and MR3 in 1/72nd. alley Cat have filled the gaps with resin conversion kits of the MR1 and T.4 to cater for the blunt nose and tail of the earlier mark. My model represents VP262 of 120 Sqn in the early 1950s and is finished in the post war Medium Sea Grey and White Coastal command scheme. Build details are given here

Briefly, the main elements of the conversion are removing the MR2 nose and tail and replacing them with resin parts. The nose is cast in clear resin and was the only difficult bit as it was not a good fit being too narrow. This was remedied by the some extra fine Miliput to fair in the nose. The model is painted with Gunze Sangyo Medium, Sea Grey and White, both being from the Aqueous Hobby Color range. Decals are from the kit and the conversion. My main disappointment with the model was an issue when removing the masking which did not come away cleanly and so the transparencies had a couple of extra coats of Klear which has lessened the impact.
Hope you like it. My next models are a bit smaller, including an MPM Hudson that is the sole occupant of my Shelf of Doom .
