Nice reference. I don't see any pilot badges that are "cut out". All examples are solid through the center. 

1938 dated looks good, these were fased out early in the war

Have a look at this link - https://www.germandaggers.com/Gallery/BW1.php

I figured it out. This cap is from the Reunification Period when the Canadian Army, Royal Canadian Navy, and RCAF were combined into the Canadian Armed Forces. I believe the maker was Principal Cap and Sportswear of Montreal. Anyone have other information? 

I appreciate all that information.

This jacket is been offered to me. Compared to others I've seen online, I think it's a good piece, what do others say?   Thanks, Paul 

Saw this WW1 Flyer badge for sale. But would like in put if an offer is worthy of a further conversation. Does the back look rough?   

This is a 1972 dated Canadian service cap as evidenced by the label and General Service side buttons. But does the RCAF badge belong? This seems like an Army pattern green cap to me with a wrong badge. Any help? 

A thoroughly destroyed Achilles , the narrative that came with photo though we would think it's statement of being from the 7th Battalion Royal Welsh Fusiliers is in error, Tank Destroyers were not organic to Infantry Battalions, same like in the American army right. No this Achilles wa no doubt from one of those Royal Artillery Anti Tank units and was in support of the 7h RWF Bn. For a Stug III in this unit Schwere Heeres Panzerjäger-Abteilung 559, it was only one company that was equipt with the Jagdpanther, the rest of the battalion's companies had either Stugs or the Panzerjaeger IV.   This M10 Achilles belonged to 7th Battalion, Royal Welch Fusiliers and was knocked out by a StuG III of schwere Heeres Panzerjäger-Abteilung 559 in Hertogenbosch, the Netherlands on 26 October 1944. The M10 was supporting its troops from the same unit who were clashing with Fallschirmjägers in the town when a StuG III appeared and engaged the British tank destroyer in a duel which ended in the German’s favor, with the M10 getting hit in front of bridge over the Dommel River on Kruisstraat. Despite this, the British crew all managed to bail out and even had time to spike the main gun with a grenade. The StuG meanwhile fired at the M10 repeatedly until it burst into flames, the fire then spreading to and burning down buildings on Kruisstratt and Karrenstratt. Hertogenbosch itself was liberated a few days later by elements of the British 53rd Infantry Division. _

Thanks
