it seemed that you guys have moved on to different things but here is some info on the original topic.
on the first page harry posted a link showing a metal master dusenberg

this is a rare kit that came with a metal body the concept was that you polished the metal on the top on the body while painting the rest. a few of the 1:1 dusenbergs were done with polished aluminum ascents.
i built this a year ago after obtained the kit from a family member that had had it since new.

the fit wasn't good but it was beautiful finished. i have since researched the metal masters line of kits and have learned that they were done in 2 series. first a dusenberg as pictured above, and a 16 cylinder
Cadillac these are almost imposable to find, at least i haven't been very successful
later another set was done, the set included a t-bird, a 52 vette, and a mg-tc
the t-bird and the vette are not very rare and average 40 bucks the mg- tc isn't rare ether but not as coman. i manged to find one at the last swap meet.

showing on the back is the other in the set

and here is the parts notice the metal body

the kits were to hard for kids to build and were disconnected fast. to be honest i had a hard time building it too.
but monogram tried the same concept a while later but in a different form. keeping the metal masters name. they came out with a few dusenberg the kits were all plastic but every part was silver plated( not chrome they rely are silver its more dull then usual chrome) with gold chrome instead of normal chrome. These kits are quite conman on ebay. here is my example.

and see everything is actuality chrome or gold.

thanks for looking and i hope i didn't bore any one.
