Managed to take a couple pictures of some good "compatible" items.
First up, from the (very limited) Prince of Persia line is the horse, Ashk.
Surprisingly, the horse is perfectly scaled with the Indy line and, as you can tell from the pics, is virtually the same proportions as Indy's horse.
It is a very well-sculpted figure, but I think the tack and bridle - particularly the saddle and saddle blanket, are pretty fancy looking to fit in well on Indy's adventures.
Unfortunately, they are NOT removable. They are glued into place. In fact, underneath the saddle is a large hole in the body of the horse with a corresponding tab on the saddle that is snugly glued in place.
Now, what you could do - and I may do if I ever get the time - is you could physically cut the saddle blanket off and around the saddle (the tab/hole is under the saddle) if you wanted to get rid of all the extra finery.
The bridle should be a lot easier to remove without damaging the horse, if you were so inclined.
The horse lacks knee articulation, which severely limits the kinds of action poses you can put him in.
The sculpt also hurts in this area, since the tail is sculpted to hang limply and, unlike Indy's frizzy-maned action horse, the horse's mane hangs limply all to one side. The sculpting looks great, but the horse very much looks like he's doing no more than a lazy trot.
Next up is the jewel in the (extremely tiny) Prince of Persia collection, the Alamut gate.
Makes a really spiffy piece of scenery for Indy figures. I have taken the liberty of removing some of the silly "action features" from the top of the gate which I had no intention of using and which, in my opinion, harmed the aesthetics. There still is a hidden play feature (fold out steps), which I also plan to never use.
In fact, I even went so far as to remove the base piece, as you can see in the second picture. The base consists of a strip of cobbled ground and rocks on either side of the gate. Didn't like the look, so I chucked 'em.
The portcullis raises and lowers with the crank, though mine doesn't seem to want to stay up anymore - collateral damage from my customizing, I guess.
I really think this is a cool looking piece. I think if you were enterprising and bought some of those schleich castle wall pieces and maybe painted them all to match each other, you could make an awesome Middle Eastern medina or palace courtyard or something for all kinds of exciting adventures.
And speaking of Schleich, last up is the Schleich Safari truck. Bought this a while ago. I think the vehicle looks generic enough that it could pass as being a period vehicle.
As the Schleich figures are not quite 1:18 in scale, it was a bit of a squeeze getting Indy to fit inside the cab, but I managed it. Sitting in the passenger side is easier.
For some reason, the truck is a right side drive (what kind of silly country would do
that?), but I think it is a spiffy looking vehicle that would look at home in any kind of Middle Eastern or especially African adventures.
I do hope to paint this truck at some point, as I'm not crazy about the design. If any customizers have any suggestions for what color they think it should be, I'd love to hear suggestions, tips, etc.
Anyway, over the past couple years I have been scouring various toylines to try to come up with compatible toys to work with the tragically small Indy line and hope to post more stuff in the future.
But, though I think all of these items could benefit from customizing to bring out their full potential, I think they are all good additions to any Indy collection.
