17th Vehicle Company

Hello, am new to this forum and have joined specifically to see if anyone here can advise as follows:

I am trying to research the WW2 history of Sherman VC Firefly, Army Census number T289477.

Originally I thought an impossible task, but Canadian war diary records indicate that this vehicle was issued by 17th Vehicle Company on  9 Jan 45 to F Sqn 25th Canadian Armoured Delivery Regiment.

So, though I can request the War Diaries for 17th Vehicle Company (and may well do anyway), I wondered if anyone in this forum would know if the British War Diaries record vehicle issue data, and if so whether it is possible to trace individual vehicles?

If not... then the next avenue of investigation is to see if it is possible to determine where 17th Vehicle Company got their vehicles from... were they issued direct from the UK, or might they have been acquired from another British Unit... and in turn where that unit got the vehicles etc.

History for this tank as follows:

Known - Aug 42 - Manufactured as 75mm by Chrysler (in first 100 M4A4 variants manufactured)
Assumed - Sept 42 - Used in USA for vehicle training
Assumed - ??? 44 - Reconditioned by Chrysler
Known - Mar 44 - Shipped to UK to British Army
Known - ??? 44 - Converted to 17pdr Firefly specification
Known - Jan 45 - issued to 25th Canadian Armoured Delivery Regt
Known - Jun 45 - struck off Service in Class 1 (best) condition by 21st Canadian Armoured Regt

So, I am trying to determine known or likely history between approx. April 44 and Jan 45... the time span is too long for the vehicle to have been in conversion (to change the tank to 17pdr firefly should have taken at most 1 week for a factory set up correctly)... and it seems unlikely to me that this sort of material would have spent months sitting in a vehicle park waiting to be issued.

Any help members of this forum can provide would be much appreciated.

Ps - I am in the process of restoring this vehicle to the road - details of the restoration are on facebook... look for t289477... unfortunately I am unable as a new member to post the link address.
