I'll cross-post my comments from the other forum for those that are no longer members. I was involved in the discussion on the old forum as well. Mark, there are a few areas of disagreement between my research and yours. But some of this is reading tea leaves and choosing which source you trust, because different sources have limited specificity and often conflict. Plus TOE's and reality often diverge.
First I posted this:
"A few years back, I spent way too much time researching this. I collected and read histories on all the units, a few combined histories, and communicated with a member of 6DCO (who sent me his limited run book on 6DCO). Below are a few comments from a brief review of some notes.
First on the Jeeps: They were on all three units (6 DCO, CIH, Skinner's) TOE, but only CIH received all its jeeps them and deployed them as troops of 6 in each squadron.
On the Heavy Armored Cars: Each Regiment had 8 M3 GMC or AEC armoured cars (The sources are a little confused on this, my best information is that Skinner's had AEC II (specific source mentions 6pdr), CIH originally had GMCs, but transferred their GMCs to 6DCO when they left Italy, 6DCO had AEC's prior to receiving the GMC's). They were officially organized in a single heavy support troop under RHQ, but in my reading I found instances of them being deployed in groups of two, as well as being the full troop. According to at least one source I read, the AEC's were not well loved because they tended to bog down and fall behind the Humbers and Carriers that were rushing to secure the next bridge after a breakthrough.
On the mortar units: In 6DCO small (two mortars + two carriers) troops were initially placed to each squadron. Later they were grouped in a single six mortar troop under RHQ that could be deployed to support a given squadron. The CIH toe shows this larger group under the RHQ.
On the greyhounds: From my notes, when 6DCO went to greyhounds, they went to two troops of three greyhounds per troop, one of four humbers, and one of four carriers.
On the double units of Humbers in Skinner's horse: I could find no real secondary source to support two units of humbers per squadron .I think the cited website is wrong.
Some additional random notes:
Here are the ethinic groups for each regiments squadrons

A few good sources include (most of these are not widely available):
Sworn to Die (Lt Col Skinner) [Detailed coverage of Skinner's Horse in the Italian theater]
6th Duke of Connaught's Own Lancers (General Indar Jit Rikhye) [Significant Italy coverage]
The Last of the Bengal Lancers (F. Ingall) [only has brief portions on Italy]
King George V.'s Own Central India Horse : the story (continued) of a local corps, being volume II. of the regimental history (A.A. Filose)[most specific Italy TOE, plus significant other Italy coverage]
The Indian armour: history of the Indian Armoured Corps (Gurcharn Singh Sandhu)[second volume on the general history of the IAC -- some summary TOEs and good info, but where it disagrees with individual histories, it is likely erroneous]

Then this:
"I don't think we need to make the list overly limited and cumbersome by restricting things to regiment specific options. Most lists have the ability to be fielded in a slightly ahistorical format. And even some options that seem ahistorical might not actually be. For example, though 6DCO did not have official jeep troops in each squadron, there are plenty of instances I have read of a SQD. HQ or RHQ jeeps being sent ahead, which would be adequately modeled by deploying a jeep troop.
Here are my thoughts/proposals regarding the list:
First, I'm excited they finally put out a list. I sent in a fan list many moons ago. I am glad that there are not any fundamental errors, only excluded options. I don't think many changes are needed.
With regard to the exclusion of greyhounds. I am ambivalent. Only one regiment (6DCO) had them from October of '44 on. They would make a cool-mixed unit, but it would add significant complication to the lists to allow the full squadron. A way to get close--without too much messing with the list--would be to say that the carrier troops could be replaced by a 3 car greyhound troop. This would allow someone to field a short 6DCO squadron by fielding three of 6DCO's four troops (i.e. EITHER 2x3 greyhounds and 4 humbers OR 3 greyhounds, 4 humbers and 4 carriers).
With regard to the heavy troop (or "gun battery" as 6DCO sources named it), I'd love to have it--though the full 8 car/gun unit* might be a little too much--possibly just a half size unit. I.e. 2 or 4 cars of AEC II or M3 75mm GMC or possibly staghounds**
With regard to the mortar troop, just a normal 2/4/6 unit of mortars in mortar carriers should work (with a note that these can be modelled as IPC's at the player's discretion with no change in rules)
I think the above would make a more accurate list without creating a ridiculously complicated list.

*I know that Mark Davies post above suggests they were units of 6 cars . . . but every source I have read says 8 cars. For instance I am looking at page 109 of Maj. Gen. Rikhye's text on the 6DCO and it expressly states that the "Gun Battery was organized in two troops, each of two sections of two guns each, mounted in an armored half-track vehicle" and the TOE I posted above from the primary text on the CIH expressly states "8 armored cars heavy"
**While I am absolutely certain of the AEC II's in Skinner's horse and the 75 GMC's in 6DCO, I have never been able confirm whether CIH received Staghounds or not prior to departing Italy.
Also though Davies suggests "DCO Lancers and Skinner's Horse were very short of Humber Armoured Cars" I think he may slightly overstate the case. While I have read a number of accounts of 6DCO abandoning knocked-out AC's and carriers, most photos show troops of 3-4 humbers or carriers. Additionally when the greyhounds arrived the humber patrols were at full strength."
