Can anyone confirm?

#2 leads to the reservoir

#1 I believe heads to the clutch actuator which is located next to the clutch.

There doesn't appear to be an existing line, just a lonely banjo left abandoned on the solenoid. I suppose the next step is to have the proper line made by the hose shop.

Would it make sense to rebuild the solenoid since it's all apart? I'd hate to find out a rebuild is needed AFTER it's all put together.  Perhaps there is a way to test it on the bench?

I hope to share some more progress in the near future. This thing has been sitting in the garage for way too long.

You are correct, the inlet is the far end https://www.pegasusautoracing....ion.asp?Product=3502 . The fitting for the banjo goes to the hard line to the slave, you could use another banjo with a very small barb for the inlet (since the reservoir hoses are very small diameter). 

If in doubt, good news is that the Master cylinder is easy to find.  My car came with a 0.625" (Girling 625), replacements on Ebay are dirt cheap (as little as $18 for Chinese copies) and match the 0.75" that you have, or 0.625 or 0.70"...Lee

These are easy enough to take apart and check least clean out any crunge in it from old DOT3 fluid (likely....).  This is a Girling .750" (CV center valve?) piece and seal kits are still around. Same kit was used up thru the mid 80's on Jeep trucks. You can also order entire units from Euro parts dealer back in OH.  He previously had them available on eBay for very reasonable money.

If you have the ability, I'd reline the original with brass/bronze....and then rekit. I did this with my original aluminum cylinder, but I believe the replacements are cast iron so perhaps not such a big deal....  Can't tell which you have.......

...and be sure to use DOT4 Castrol (Girling compatible) brake fluid when refilling!

I believe that your drawing is correct now that I look at it and a couple others....   Not having car to stick my head in and look is the pits!    

I always thought that the pressure port was at the end.....not the middle!  Like  brake M/C.   But I guess if that end port is blocked off during the piston stroke, you won't have fluid going up into the reservoir!   Seems backwards....... but I found other drawings showing similar with reservoirs at end port!
