AVRO CF100 Pedals

I have obtained a couple of AVRO Canada Pedals which I am assuming come from CF100 – they match photographs and have had in-use wear.

Can any one tell me what are the inspectors stamps/markings specific to the CF100? So that I can be absolutely sure…

The two pedals have a plethora of markings

Pedal 1 –

HO5822 on side
3123481/7; S and 13 in circles 13378 and other markings on face
X813 and X733 on side – last one Xed out

CS-C1272; 15S 1 and MA291-3 on rear

ALCAN and CS-C1271? and MA286 on foot

Pedal 2
X1056 X on side

same markings on back.

No markings on front

ALCAN X1167 CS-C1271? on foot

As well as the Large AVRO CANADA badge on front.

Both have a DOWTY of Canada master brake pedal cylinder at rear.

Thanks for your help
