File talk:GWR 104621 Mink 'A' Covered Goods Van.jpg

According to the Index of Wagon Diagrams in Atkins et al volume 1, wagons built to Diagram V18 included both MinkGWR telegraphic code signifying a covered goods van and MinkGWR telegraphic code signifying a covered goods van A versions. Lot 919 is shown as MinkGWR telegraphic code signifying a covered goods van A (numbers 104001-499, typical tare 6t 17cwt) and Lot 920 as MinkGWR telegraphic code signifying a covered goods van (numbers 104501-105489, typical tare 6t 8cwt).

104621 fell in Lot 920 and is painted with a tare of 6t 8cwt, which the Index suggests makes it a MinkGWR telegraphic code signifying a covered goods van. However Atkins et al volume 2 confirms that the MinkGWR telegraphic code signifying a covered goods van A is the ventilated version. 104621 is ventilated, and the Railway Heritage Register Wagon Survey has pictures of a number of other Minks in the range 104501-105489 all of which are also ventilated. All are thus correctly described as MinkGWR telegraphic code signifying a covered goods van A as per volume 2, which leads me to suspect that the type descriptions may be transposed in the Index, ie Lot 919 should be MinkGWR telegraphic code signifying a covered goods van and 920 MinkGWR telegraphic code signifying a covered goods van A.

Update to article of the week to follow in due course. --Robin (talk) 17:04, 13 November 2017 (UTC)

There does seem to be an exceptional amount of confusion online between MinkGWR telegraphic code signifying a covered goods van and MinkGWR telegraphic code signifying a covered goods van-A, with several sites perpetuating the apparent error that Lot 919 is MinkGWR telegraphic code signifying a covered goods van A and Lot 920 is MinkGWR telegraphic code signifying a covered goods van. Annoyingly, the one surviving wagon from Lot 919, 104040, also apparently has vents: link. However, perhaps that's a later modification... --Danny252 (talk) 13:43, 15 November 2017 (UTC)
