Need Help With Belgian Railway Stamps Of 1920, Scott Q94-Q102.

I believe that in 1920 there were 3 headlamps on the train stamps, and only 1 headlamp on the redrawn set of 1920-1921, Scott Q117-131. Could someone kindly post where the 3 headlamps were since the cancellations on my stamps make seeing things challenging?

One headlight on the smokebox door, and two smaller lamps above the buffer beam. The smaller lamps are removable- in UK use they act as a code, e.g.one lamp for goods train, two lamps for express train- so I suppose the same for the SNCB.

Didn't notice anything about 3 headlamps on the 1920 set in the Stanley Gibbons specialised Belgian catalogue, but I haven't got my copy with me.

As far as I can see, the lantern at the top of the front end of the boiler has disappeared in the redrawn design. The two lights at the front of the frame remain.

Oops- was looking at the wrong set. I've seen some bad drawings of steam locos, but that one really takes the biscuit! Probably a Dunalastair class loco.

Aren't the value "tablets" an easier clue? They're very different between the two issues.

Yes, they are. But that was not the question. :-)

Yes, cjd, and thank you for your note. You are absolutely correct, and for most stamps, what's beneath the value reveals the stamp's identity. But unfortunately, that is not the case say for the 1.10 franc value, which is why I needed the help locating the headlamps.

Many thanks to all of you who helped me to identify the stamp in question. All set now.

Using the 1.10fr example, one issue has an outline around the value, while the other does not.

If there are a bar and dot under the FR, there is an outline. This also applies to the 1.10, 1.20 and 1.40 values in that set.

If there are two bars under the FR, there is no outline, and again, that carries over for the set.

When you're stuck with heavily canceled stamps, more clues are always nice to have.

Once again, thank you Cjd for your most helpful post on other ways to identify these stamps, canceled or mint. I am most grateful.

From Gibbon's "Belgium and Luxembourg" - "In Type P 72 the engine carries three headlamps instead of one, the make-up of the train is different, and the last coach is clear of the curved line of the frame. The lettering at the top of stamp is smaller".

Judging by the illustrations in the catalogue the tender of the loco has been redrawn- should be a lot easier to spot than the headlamps.
