Speaking of Il-10, there are Russian monograph books from Aviakollektsya 2004 and 2005.
Poland
136 Il-10 - they were gone by 12/59 (now 12/68!) (confirmed also by Polish sources). It's a detail, but first were delivered in 2/49 (now 1/49).
They were always plain green only (icon 3117 would be better, even with Czech(?) markings). The same for unit
952 Avia B-33.
It's worth to add a variant of Il-10 with two 250 kg bombs, without rockets. There could be also a variant with 4x100 kg.
Czechoslovak OOB:
158 Avia B-33 has Soviet icon, should be 3117. A detail, but according to the Russian book, their units were disbanded in 8/60 (now 12/60), the same for
136 Avia B-33.
As for the latter one, to be precise, Czechoslovakia manufactured B-33 with 4 guns 23 mm from 12/51 only, so they could have appeared from 1/52 at the earliest (now 8/50). Before that Czechoslovakia used Soviet Il-10 with 2 guns 23 mm and 2 MGs, delivered from 8/50.
Romanian OOB:
134 Il-10 Stormovik - Romanian Il-10s are also shown in books as plain green. According to the Russian book, delivered in 3/53 and withdrawn in 1960 (now 1/53 - 12/58)
Hungarian OOB:
135, 136 Il-10 Ruszkov, 137 Avia B-33 - the same with colours, always shown as green (examples:

Bulgarian OOB:
388 Avia B-33 - since they were Avias, the armament was 4x23 mm. I've found no color silhouettes (Bulgarian ones are quite obscure), though I assume, that Czechoslovakia delivered green ones.
North Korea:
130 Il-10 - they should be armed with 2x23 mm and 2 MGs. Undoubtedly also bomber variants were used.
China:
136 Il-10 - they should be armed with 2x23 mm (now 4). Again, always are shown in a plain green color. According to the book, delivered only from 1950 (now 1/46). Undoubtedly also bomber variants were used.
That's all as for now (unless I find something interesting)
