Thank you Blaamand.
What a fabulous provisional overprint link
It looks like my GALATA suggestion is incorrect, I'll spend some time
perusing the material tomorrow.
I am a newbie with Turkey, closing in on a complete BASIC collection,
missing about 100 stamps up to 1983 (excluding Anatolia -Turkey in Asia)
Now I need to get a decent catalogue to isolate the varieties, just not sure if I want to go there.
I would have no skill at all with Postmarks, so that exciting area would be lost to me.
But the "Republic" issues could be experience all of it's own, with shades and paper thickness, and perf varieties.
I've really enjoyed the journey thus far, wasn't that expensive, most stamps
were available on a meagre wallet.
I have learnt there a lot of Turkey collectors out there, it seems very popular.
