I think it looks like a home brew job too,but it looks like they knew what they were doing.Our undertaker would have used something like that if he could have gotten his hands on it.He was the only one,you used him or got buried by family or friends.When I was a kid he used a Checker 12 passenger stretched out airport station wagon.He gutted it,had it painted and the windows painted too.It looked nice,if you wanted a flower car you supplied your own.If it got 50 miles put on it that was a busy year.
