The color of the box and the style is the same on the attack sr second gen.

Kyosho TX on eBay - broken, incomplete & dirty, but still obviously a Futaba T2DR.

 

Another T2DR variant. Not exactly transmitter, but controller from RC simulator RealRace. The box and sticker says it is a Genuine High Quality Futaba Controller. 
(The other controller option looked like a T2PB pistol grip radio which conveniently is covered).

Nice find  

Yet another T2DR based TX - the Schumacher "Response":

 

Evening. Being honest I'm not a Tamiya person but wanted to add a few notes as this post had been highly useful for figuring out what system was likely to be on the Mardave Maruader.

Regarding the 'Medallion “M” Series (Mark II?) FP-2GS' & Mk3 it appears that these may have been the same transmitter but a big distinction between the two being a change of receiver and servos. The Mk2 had the S23 servos (square outputs, male pin sockets, twisted wires). The S23 are the same as the FD33M aside from the sticker. Ripmax rebranded the UK ones to FD33M just to confuse us in years to come!

The Mk3 had servos with 25 spline drive along with the J Plugs. There were changes on the signaling to with neutral being 1.52ms rather than 1.31ms as it was with the earlier S23 servos.

Here is the clarification I got from the UK Futaba service email:

"The Futaba S23 servo was rebadged for different distributers. In Germany it was sold by Robbe and was called the S20. Japan and America kept the S23 name and Ripmax in the UK called it the FD33M. It was a general purpose servo using the old 1.31mS centre specification and have the 3 pin male connector and twisted wires. This system was known as the “M Series” in the UK. Later on the specification changed to what was known as the “J series” which used the current 3 pin Female connector with a flat lead and 1.52mS centre spec. The newer “J Series” servos often had a 3 digit number starting with a number 1. The FD33M was superseded by the S28 servo which became the S128 with the current lead and centre. This in turn became the very popular S148 which sold for many years and has only recently been discontinued."

Thanks Doc

Was the Futaba Medallion 2 ever sold as 40mhz?

Just bought this one from ebay, but it has arrived with a 40mhz crystal in it. I am not sure if this has been put in by mistake or not!

Will is do any harm just to try it with 27mHz crystals to see if it does talk to my FP-R2GS 27mhz rx? Will that damage it if it is actually 40mhz?

No matter with crystals. You only haven't respons.  If you have an apaired crystals in 40 41 or 27 26 mhz try them. And you'll know.

Thought this was interesting: Futaba Medallion 2 27mhz RX/ 2 servo combi unit (spotted in a 1/8 Mardave Capri RS on eBay - www.ebay.co.uk/...6167309134)

 

I guess I looked at this too quickly to realize that this is some sort of all in one receiver and 2 servos. Really cool, never saw anything like this before.....
