MG34 parts
 

I went to a coin shop today looking for german badges. He had an original MG34 dated 1941 all but receiver. I know you can pick up a dummy receiver for cheap and have a great conversation pc for a collection. I see them go for 800 to 1600 a set. He said he wanted 350 for the group. I picked it up but will be listing it on gunbroker for 650$. Any opinions of this buy?
