I will happily answer any questions people may have.
Not so much questions, but I have a few opinions and suggestions I will share.

Firstly though, great additions to what is pretty much the definitive (or indeed only) 20mm range of Rhodesian Figures. Besides PATU and GF you've also covered INTAF and RR reservists with these additions. A few more couldn't hurt though.

1) The range needs more radio operators - the RLI and RAR stick leaders all carried them, so that's 1 radio per four men... maybe a pack of these? Other units had fewer of them, but they were easily as common as an FN-MAG.
2) I don't recall seeing any figure in the range with a 32Z Grenade mounted on his FN. SOP was to have one ready to go and it would be the first thing fired at an enemy position. Small beans really though, but if you were planning some further additions...
3) Nice to see the Bren Gun make an appearance! Very common in almost every unit outside of RLI & RAR. Lesser appearances were made by such weapons like the Sterling, 'Rhogun' and the AR-15... a pack of 'odd' weapons might be a nice addition to break the regularity of FNs for RR and other similar '2nd line' units.

Sterling with RR unit.

SMLE No.2 - as the Army was expanded late in the war there were not enough FNs to go round and priority went to the regulars and the 'Nashos' of the RR Ind Coys (actually 'RAR' Ind Coys by this time). About 1978-79-ish as the unit is de-segregated.
Note in both photos the white guys have cut-off or short sleeves, or have them rolled up, while the black guys have mostly have sleeves down or slightly rolled. A toss up between what was worse, heat or insects.

AR-15... no idea which unit, but I would guess RR or PATU.
4) How about some more ZANU? Twelve figures pretty much covers it for them Pre-1976, but after that they were appearing in platoon-sized units over the border. Of course they could also be used for Selous Scout units.
5) Some heavy weapons for ZANU/ZAPU would be good. Again Post-76 they were dragging B-10 RCLs and Heavy MGs over the border and of course had them in the camps. DShKs and SGMs on either AA tripods or their old wheeled mounts were encountered. DShKs also found their way into Rhodesian base defences by the obvious route of being captured too.
6) FRELIMO - Could also be used for ZAPU 'regulars'. Somewhat more regular-looking and uniform than the guys you already have.

Samora Michel and friends well turned out for the camera.

FRELIMO Mortar Team... not the one guy's turn for the unit's boots.
7) Rhodesians in helmets. Not common, but not unheard of either. There is a picture or two of the RhSAS and RAR in them out there.
