SdKfz 10 Halftrack

[Jaeger]

The upgrades to mount anti-aircraft and anti-tank weapons upon it.
Also to have various artillery for this vehicle to tow. 

[Tracks]

Right, what are we all going to ask for next? :p

M3 Medium tank (Also known as the Lee or Grant)
or
Panzer II

Also to have various artillery for this vehicle to tow. 

Rubicon Models already has available very good and very useful artillery pieces:
German Flak 36/37
German Pak 36
German Pak 38 or 97/38
German Pak 40
The latter three were commonly towed by the SdKfz 10. The 88 (Flak 36/37) of course would be a bit too big for the little SdKfz 10 to tow over long distances. However, no worries because Rubicon Models also offers the SdKfz 7 in plastic kit form  to tow the famed 88.

I second the M-3 Lee/Grant

I second the M-3 Lee/Grant

Pretty sure they said the M3 medium was due at some point as they were using VVSS with the return roller directly above the boogies for it. Would make me wonder which mark of M3 medium they would make, or if they’d do the same as what they did with the Sherman kits.

Even if they don’t release all of the marks to begin with, they could still design it that way just incase.

How about a resin M2 medium kit? Just count all the MMGs...

Various marks of the Lee / Grant could be made if the hull sides were molded flat with you adding the doors/ vision ports  to sides depending on the version your modelling . The different style / size rear stowage boxes , groucer stowage boxes ( on glacis and over the driver ) , later model armored fan covers , bow MG plugs , and even the longer 75mm and counter balanced 37 could all be separate add on ( drill out a hole ) piece . Its the engine deck / rear plate exhausts that might be a pain , but who needs the diesel version of the Lee anyway ? The road wheels / track will be sorted once the early M4A1 kit is released

Yes, Rubicon did say that they would make the early VVSS suspension for the M4A1, and have the suspension available for use on upcoming M-3 Lee/Grant tank kits,and the M-7 Priest.
 I seconded the suggestion by Elias because I'd really like to see a plastic M-3 Lee and a M-3 Grant kit.

I'd love a cast hull Lee.
It looks so cool.

[elias.tibbs]

Everyone else does he riveted hull, so it’ll be different.

[ripley]

All though very cool looking , both versions of the cast hull never made it into combat , training only . Although one does show up in Bogart's 1942 movie Sahara as a wreck , so pretend combat then

[jamesvalentine]

That's the great thing with a company wanting to cater to modellers. They have no excuse not to do the cast
