I have an original MG08 Trench Mount for sale on EBAY. The EBAY number is 180575732197
I have recently compared it to an IMA reproduction. After this comparison I am certain the one I have is original. There were a number of differences in the workmanship and the one I have has some minor rust pitting. The starting bid is $650.
I have also attached a few photos.
I hope some of you have an interest in this one
