Why unknown type? According to German documents the Danish bunkers are of type 632.dirk Peeters wrote:for arthur
since you don t care
why should i care
you have your opinion which is perhaps the right one , i have mine
perhaps take a meter with you and look after the typenheft afterwards like we do
i cant give you the exaxt locations because i don t know the type
measured in brest , lorient , st nazaire and danemark 9 turretbunkers unknown type because the dont fit the typenheft plans
have found plans for belgium and walcheren and again no match

It's not surprising that the actual measurements don't exactly match the Typenheft, because the undetailed Typenheft drawings are not construction plans.
Going by the Typenheft, the defining characteristic of 632/648 seems to be given by the choice of turret. The turret type then dictates the layout of the turret room (height of the room, number of air filters, ...). So, if a 3-embrasure turret was used, the bunker very likely is a 632, otherwise if a (Czech) 1-embrasure turret was used it very likely is a 648. You might not find any other conclusive differences (but of course that doesn't mean you shouldn't look for them).J. Andersen, R. Rolf, 2006 wrote:Standard design bunkers of the same type are often regarded to be executed identically. That is, however, not the case. The Regelbauten as published centrally in type books had a type number with its function and a number of nominal quantities of building material and equipment. These data gave a basis for choice and construction planning. When these were approved an application was sent to the central engineers office that worked out detailed drawings of each individual bunker wherein the local geographical and tactical situation was taken into account.
