How can you see if an Oval is a war production or post-war?
And what are the average prices of the following ovals: 501, 502 and 506?
In my opine...as with anything price is relative to the authenticity, condition, provenance and demand for that item. I have seen the market for legitimate WWII US Airborne items go through the proverbial roof lately (let me say that I don't mean to discredit any other area of collecting this just happens to be my area of interest for quite some time). So, to answer the question as to what they are "worth" would be difficult.
Looking at the pictures of ovals in this thread there are some nice items. I have been away this week and will post a few that I hope people will be interested in.
