I thought there was a third type of frame introduced with BT7 1528.
Hello Josef,
You're correct in that the type of bow introduced at 1528 was the "third"
type, as the "first" was the 'permanently fixed to the car' type used on the
first BN 4's. The "second" was the 'thin-legs with pegs' type, and the "third"
type the 'fat short legs with no pegs'. I didn't mention the first type
because it was not removable, and only applied to the first four-seaters,
whereas the removable types could be "mixed up". This is the revised caption
I just sent to Derek Job with the three top frame pictures which I sent to
you:
< The first top bows used on the BN 4 (Part No 14B 6793, finishing at BN 4 #
68959) were permanently fixed to the car and the feet slid in short channels,
as shown in the Longbridge BN4 Handbooks. They were helped to stay in place
by an "L" shaped rod attached to the main leg plugging into a "bonnet prop
rubber" fixed to the wheelarch.
The late 100-Six/ early 3000 (Part No. AHB 8354 commencing BN4 # 68960) top
bows can be easily distinguished from the last style of bows used on the 3000
and 3000 Mk II. These bows look similar to the first "fixed" type, except for
now being removable from the car. They are made of 16mm (5/8") diam. tubing
and have cranked, or bent main "legs" with pegs protruding from the bottom
that plug into the smaller diameter hardtop sockets.
The much sturdier bows introduced early into the 3000 BT 7 run have shorter,
larger diam. (20mm-13/16") main "legs" without pegs, that fit into the larger
diameter sockets originally just reserved for the tonneau cover bow. (Part
No. AHB 8787 commencing BT 7 #1529)
I have enclosed pictures of the two removable top bow types side by side.>
Best regards
Peter
