I wouldnt bother ....a regular old Mercury was a lot better.
There was a real issue when Milbro called their guns Dianas ...pressumably to get them seen as similar to their German high quality counterpart but they got around it because Diana was a company name in Germany but not a specific model name. So Milbro Diana should be the correct name not Diana as a singular name.
The guns share nothing with the Diana company.
A cheapy Diana 34 would utterly trounce it for fun and i just never believed the rave review in AGW for the G80 at the time ....it was poor.
