Tea1980 I didn't look for the exact base, but I think he used an aging morph. There are more 'mature' models available with G8 than G3. Most of the G3 models I have loaded on my base DAZ installation (~ 580) seem to be younger looking than his version of Mom. Maybe if you ask
lexx228 nicely.
BTW, I had figured out the hair asset right after I posted my question, what made me unsure was that his model seemed to have shorter hair than Bronwyn but I think that was just the style choice he made.
For older base models on G8, I prefer starting with either iSourceTextures Adriana or with FWSA Edith, making sure I both scale and shorten the height of both to make them between 160 cm - 173 cm tall. The combination of Scale and Height seems to work out better than just Scale alone (BTW, Measure Metrics by default uses 'Scale' only to change height.
