Bunkerbarge Posted January 9, 2020 Share Posted January 9, 2020 If it was operational it would need the converted personnel coach as well. Mine is set in 1947, the year the gun was decommissioned, so assumed to be no longer operational! 2 Link to post Share on other sites More sharing options...

RMweb Premium PhilJ W Posted January 9, 2020 RMweb Premium Share Posted January 9, 2020 On the subject of wagons and coaches there are two interesting vehicles in photographs in the book 'R-O-D on the Western Front 1915-1919' by William Aves. The first is a 6-wheel passenger brake van that although belonging to the French Nord company was very British in appearance and size but with a pair of strange ventilators on the roof rather like large pent roof dog kennels with louvred sides. The other is even more interesting as it shows the German rail gun captured by the Australians. Attached to the rear of the gun was a modified open goods wagon. The wagon was fitted with a pent roof raised above the sides and appears to be used as a magazine wagon. It started out as a high sided wagon fitted with central cupboard doors about 4-5 feet wide, is about 22-24 feet long with a wheelbase of about 15-16 feet. The pent roof is raised above the sides (5-6 feet) by about a foot or so and completely covered in except for 4 square windows/loopholes cut in the sides. 1 Link to post Share on other sites More sharing options...

Kai Posted June 19, 2020 Share Posted June 19, 2020 According to Ian Hogg's books on artillery, the following lengths of the gun apply: 13.5" gun: 625.9 inches, bore 45 calibers 14" gun: 648.4 inches, bore 45 calibers 18" howitzer: 648.4 inches, bore 35 calibers The lengths of the 14 and 18 in pieces are identical - no surprise, both were manufactured by Elswick and were intended to be interchangeable on the same carriage. The 13.5 and 14 in guns both have a caliber length of 45 - also no surprise, as both were designed as battleship main guns, the 14 in gun slightly later (and larger) than the 13.5 in gun. Now, the difference in gun length between the 13.5" gun mounted in GLADIATOR WW2 and the 14" gun mounted in BOCHE BUSTER WW1 is 22.5 inches, this amounts to 7.5 mm in 00 scale (1/76.2). Judging from photos, the barrel lengths (muzzle position relative to the buffers) seem identical to me (which they should not be). Does anybody have both models available for a direct comparison? Next, gun caliber. My BOCHE BUSTER model (OR76BOOM01) has a muzzle opening clearly exceeding 6 mm (6 mm is the scale caliber of an 18" howitzer). The muzzle should be 4.67 mm to match a 14" gun (and 4.5 mm to match a 13.5" gun). These observations lead me to ask the question: Do we in fact have the same model of the 18" howitzer dressed up as either a 14" gun (BOCHE BUSTER WW1) or a 13.5" gun (GLADIATOR WW2)? 1 Link to post Share on other sites More sharing options...

I can recommend a decent razor saw..... Also a shop that sells the right aluminium tubing to line the barrel of the howitzer to be an acceptable size for Gladiator. Happy days.

craneman Posted June 19, 2020 Share Posted June 19, 2020 Chop the barrel of a .177 air rifle and you'll have a rifled barrel of very close dimensions for the two guns, use a .22 rifle for the howitzer. 2 Link to post Share on other sites More sharing options...

craneman Posted June 20, 2020 Share Posted June 20, 2020 I have no idea, but the hole in the middle is remarkably close to the right size. The rifling would probably not be to scale though. A better bet for most scenarios would be to fit a tampion, which would probably have been fitted all the time except when the gun was firing. 1 Link to post Share on other sites More sharing options...

sandwich station Posted June 20, 2020 Share Posted June 20, 2020 (edited) The model is right for Boche Buster when she was an 18" rail gun but not 14" And the models of Boche Buster and Gladiator are the same model painted differently Edited June 20, 2020 by sandwich station 1 1 Link to post Share on other sites More sharing options...
jcredfer Posted June 20, 2020 Share Posted June 20, 2020 The barrels were very similar external dimensions as the 18" was howitzer, with a smaller charge, so it had thinner walls, then the 14" Gladiator gun, which used a larger charge and needed thicker walls, for the greater range. Adding a liner to the model reduces the caliber of the Gladiator gun nearer to the dimensions of the 14" gun. It's not exact, but a slight improvement on out of the box calibers.
