Hi to all, Hi Jeffrey,
hi DutchSteam,
Worth a try :
Company Vectracom in Paris, France has been operating since 2001 to transfer archives on vintage VTR/VCR formats to newer media.
The company was founded by 3 ex-SFP engineers, the SFP was the production branch of the three state-owned French television channels (ORTF era).
They have an extensive array of vintage format machines: 2" Quadruplex, 1" type B and type C, U-Matic, BVU...
Try contacting them through their contact page & inquire if they have Ampex type A machines & IVC 700/900 series.
The Ampex VPR-1 (type A) was quite popular in France circa 1978 and French regional TV France-3 had many Ampex VPR-7900 Series 1" type A VTRs. IVC 1" machines were also popular as master players to VHS duplication banks at the beginning of the home video craze.

see an RCA 2" Quad in this article about Vectracom :

Having Quad machines, Vectracom probably has the magnetic fluid viewer to see edit points on 2" tape.
They could probably identify your recording format via tape revelation.
As PPP-Penguin mentioned, 525/60 type A VTRs are probably non-existent on this side of the Atlantic.
Good Luck &
Best Regards
