"L�¼ger Sternlicht"???

[Ron Wood]

The gun described by Mr. Ludlum is a product of his "literary license", it makes a good story but has no basis in fact. There were some aftermarket scoped Lugers assembled by Pacific Arms in the 1920's but I seriously doubt that any of those made it into the hands of the Gestapo. I also suspect that Penem�¼nde was guarded by the regular army rather than the Gestapo. Guard duty is not glamorous and the rain, snow and mud would get their pretty uniforms messy.
By the way, there is no umlaut in Luger.
A telescopic sight would be called a "Fernrohr". A Sternlicht to me would indicate a "starlight scope" and I rather doubt such technology was available in WWII, especially not small enough to be pistol mounted. I saw a very unusual Luger at a NAPCA show that is proported to be one used by Hitler's bodyguard. It has a flashlight attachment.
