George,A couple of size-comparison photos for you.Even with the 98 being a larger machine, it is "light" compared to picking up the SG1..
If anyone needs a repro paper support for an SG1/SG3...now available on eBay.I have purchased several of his typewriter feet offerings and they are high quality.https://www.ebay.com/itm/177284238728?_skw=olympia+sg1&itmmeta=01KBD0Q2326G7CZDM4KYJ1QYZ1&hash=item2946f6cd88:g:edQAAeSwslFofxIM
