Vintage 1979 SW Falcon MISB

[jawa]

Hi, not posted for a while and wanted a rough valuation for my vintage MISB falcon.
It's a SW 1978/79 sealed in original box and protected in acriylic case. In excellent condition.
Have attached some photos below

Many Thanks
Kevin

Thanks. Do you believe grading adds any appeal or value?
