The Groupy was typical of the sort that follow U Tube Reviewers. I don't normally watch any of that cra#, but had the misfortune to see a well known UTube person reviewing a not very good sample of the 15XX. The review was unbelievably confusing, rather niaeve and cringingly verbose. First it was super and then it was poor and that took over 30 minutes.

Absolute bollox really. Put loads off even buying one to try out!

I'm afraid I also told the bloke that Railway Engines don't have Funnels!

> The GWR only built the 15XX as the S100s they tried to buy from Newbury were poor quality.

And yet according to the records at the NRM the GWR were already designing the 15xx in Jan 1944, long before the SR bought any.

The difference between a pannier tank and a side tank on a locomotive without a footplate can be regarded as somewhat notional. Even more so if it has outside cylinders and valve gear. Some people get very excited about it, making claims about where the weight is supported makes a difference, things like that, which at times verges on angels and pins territory.
For my money if the top of the tanks are roughly on a level with the top of the boiler its probably a pannier tank, and if the bottom of the tanks are roughly on a level with the bottom of the cab sheeting its probably a side tank, and the existence of the 97xx condensing tank engines nicely demonstrates how futile it is to get excited about rigid definitions.

When you wrote "I don't normally watch any of that cra#," I actually throught you meant craft at first 😄
