From photos I can't see that the fletner vent had any detail on the prototype (it could have, just can't see on photos). It just looks as if it's a smooth cover. Hard to tell really. Maybe the detail has been exaggerated like the timber work on the Austrains CWs?
I don't think the model is being scrutinised badly. I think it's had a great wrap. If the nose is wrong, pointing this out is ok, just as people do regarding most model versions of the streamlined 38 class. From memory I thought the PL 48 received a fair amount of flak. Particularly in regards to it's sickly looking crew!
It's funny how so many models are produced that have the same features, for instance it seems that up until the Trainorama 48 most 48 models have had more nose angle. Were previous attempts just sort of copied and with the Trainorama version it has been righted. Or, has an incorrect drawing been used for reference with this latest attempt? Who knows.
I am not sure if its wrong or right, will be interesting to find out. It doesn't worry me too much, I won't be chopping anything up ha.
I simply had a few 48 class model version handy and thought a picture may be interesting.
I don't disagree with what you say, interesting that no measurements have come regarding them, yes the fletner vents had a cap over the top, so I stand corrected I do believe there was some type of extraction in them rather than just a covered tube, as you would know coupled with the stench in the hood along with the heat simple caping would not have worked. With some of them before the vents were fitted & fitters could not seal the doors properly for draft proofing even at slow speeds the heat/cold & smells came through the hood door.
Certainly your photo's show up a degree of differences in the models, but one thing I remember when climbing on board any of the 48's at the short end, was that you had to actually go slightly towards the front of the body once at the top, to actually not touch the front of the hood, so I am not convinced that the step is actually wrong as indicated by one, also if the angles of the other models are correct it would have enhanced that need to have a greater change of direction than what you did. Likewise if you were getting back into the cab after ground changing of the staff at unatended crossing loops you got up that side & walked across the front, so such an angle would be noticable in how one carried out such duties.
Although as other drivers who got in on the drivers side the bogie & brake cylinder piston link were handy steps & used when getting up for the drivers side duties.
Also consider the way the top of the 48's are in conjunction with the box lights & headlight, I beleive the Bergs is far too sharply angled with much causer box light's also the headlights while protruding out past the box lights being good replication, I suggest is too much, PL better & the TOR a touch thin (headlight) at least on the overhead shots of yours, but in the other photo's it looks ok.
In the end the problem is (& I also accept the aspect re the sand box covers look to be too far from the outer edge,) is how far do we look for the slightest error, in any model that is produced these days, & that is if it is proved, but based on a 2nd person report of some conversation with an unknown taxi driver with older retired man from TOR saying the nose was too narrow. I have heard from others who have been told from those at the shop that this model is a full new tooling & not a reworking of the old one done at SDK, thus I would expect corrections being done, at least hopefully so.
